Food Processing: Belt Scales Improve Tomato Processor Efficiency and Productivity

Belt Scales Improve
Tomato Processing

The following post is a case history on using alternative technology to improve large scale food preparation process.  You'll read about how belt scales outperformed legacy equipment for a tomato peeling process and increasing yield.

Application:

A tomato processor located on the Pacific coast uses the latest technologies in peeling, dicing, and packaging tomatoes. They were preparing to replace some of their older weigh feeders because of declining performance. One of their main concerns with installing new weigh feeders was the cost of moving the existing conveying systems in order to accommodate new weigh feeders.

2 Wire, 3 Wire, and 4 Wire RTD Sensor Connections

Industrial temperature
transmitters (courtesy of
Siemens)

Industrial temperature transmitters are devices that measure the temperature of a process and provide a measurable output over some desired temperature range. Industrial temperature transmitters primarily use either of two popular temperature sensors - the thermocouple or the RTD (resistance temperature detector). The RTD changes resistance as process temperature changes, while a thermocouple provides a changing micro-voltage with process temperature change. RTDs are inherently more accurate, but require excitation voltage. There are three style RTD's - 2-wire, 3-wire, and 4-wire.

Proper connections for all three types of RTD sensor to a user- configurable transmitter are shown in the following illustrations:

Proper wiring of RTDs

It is critically important to note that the common connections shown by the symbols for 3- and 4-wire RTD sensors represent junction points at the sensor; not terminals jumpered by the technician at the time of installation, and not internal jumpers inside the transmitter. The whole purpose of having 3-wire and 4-wire RTD circuits is to eliminate errors due to voltage drop along the current-carrying wires, and this can only be realized if the “sensing” wire(s) extend out to the RTD itself and connect there. If the transmitter’s sensing terminal(s) are only jumpered to a current- carrying terminal, the transmitter will sense voltage dropped by the RTD plus voltage dropped by the current-carrying wire(s), leading to falsely high temperature indications.

Combustion Analyzer Adds Higher Level of Safety by Measuring O2, Combustibles, and Methane

The reliable identification of low combustion oxygen in a fired heater or boiler has always been critical to the effectiveness of the Burner Management System for proper control and safety.

Low emission burners and aggressive firing control points to achieve increased efficiency and emission reductions have driven the industry to tighter control measures. But tighter control measures also hold a greater potential for combustion events. Reducing the risk of a combustion event has become a priority and has led to the implementation of Safety Instrumented Systems (SIS). This additional layer of safety is added to the Basic Process Control System.

The WDG-V has been designed to provide an additional layer of safety with the measurement of excess O2, Combustibles and Methane and by using these measurements to ensure the safe operation of the Burner Management System.

WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as well as CO and methane levels. Information from the Gas Analyzer allows operators to obtain the highest fuel efficiency, while lowering emissions for NOx, CO and CO2. The zirconium oxide cell responds to the difference between the concentration of oxygen in the flue gas versus an air reference. To assure complete combustion, the flue gas should contain several percent oxygen. The optimum excess oxygen concentration is dependent on the fuel type (natural gas, hydrocarbon liquids and coal).

Lost Plant Air a Hidden Source for Energy Savings

Save energy costs by reducing
consumption of plant air.

Industrial plant air is one of the easiest sources of power to transmit and use. It’s also one of the most costly to generate. Information from the United States Department of Energy (DOE) indicates a wide variety of factors determine the cost of compressed air. These include, but are not limited to, local electrical energy cost, efficiencies of electric motors and compressors, load factors, and service time.

Plant maintenance are becoming more aware of air leaks and the subsequent increases in cost to overcome lost power because of those leaks. One of the major culprits for lost air in a plant is the pneumatic control valve positioner and the air required to operate them. In a typical process plant, there could be hundreds of control valves. Each control valve uses a positioner to move the valve actuator, based on a set point signal from a controller.

Control valve
with Siemens SIPART

It is the control valve positioner where the greatest air consumption savings lies.

Years ago, when electricity was cheap and when valve positioners were first introduced, plant maintenance and engineering were not concerned with something called the “bleed rate” of the positioner. Over the years though, plant personnel lost track of bleed rate and pretty much forgot that a positioner is just part of the system and it operates on air. Today, a modern process facility such as a power plant, refinery, or chemical plant can have several hundred control valves with positioners. The combined air loss due to the positioner “bleed rate” can be significant.

Siemens SIPART positioners

An immediate solution to this problem is to replace the control valve positioners with modern, energy-efficient, low-bleed models. One model, the Siemens SIPART PS2 has a proven track record of providing substantial savings to large plants. In one case, a tabacco company that had 2500 positioners was planning on spending $600,000 on a new compressor to increase output. After reviewing the capabilities of the low bleed positioner and running some tests, the plant decided to implement a plan for replacing the positioners which mitigated the need for a new compressor.

The significant change in technology came with the adoption of the adoption of a piezo ceramic valve block in low bleed positioners. Traditional positioners used an I/P and spool valve which both leaked air. Over time the leaks from these two parts is significant.

Could you and your plant be in the situation where lost energy efficiency through leaky positioners is costing big bucks? If you’re even the slightest bit concerned, call in an applications expert now for a system review.

Adhesives Manufacturer Saves Energy and Stays in Compliance with Flammability Anayzer

Flammability analyzer increases
safety while lowering energy cost.

A large manufacturer of adhesives needed to reduce energy costs in their plant. A large part of their energy cost was literally going out the window in the ventilation system and associated fuel costs. The heated air they produced for ventilation was expensive, yet is was necessary in order to comply with the NFPA's (National Fire Protection Association) standard of 25% LFL (lower explosive limit) on solvent vapor concentrations.

The 25% LFL applies to areas using just ventilation, but increases to 50% LFL if a continuous flammability analyzer is installed. If the manufacturer installed vapor analyzers, they could reduce the amount of energy on ventilation and fuel.

To meet the objective of lowering energy costs, the company installed PrevEx Flammability Analyzers, manufactured by Control Instrument Corporation, on each adhesive dryer. The PrevEx is a flammability analyzer for lower flammable limit monitoring (LFL/LEL) designed to provide fast response time (less than 1 second), capable of quickly changing gas concentrations, and with failsafe performance.

PrevEx flammability analyzers use a heated flame cell and an integrated controller that continuously measures total flammable vapor concentrations from 0 to 100% of the Lower Flammable Limit (LFL) range. To avoid condensation during sampling, the entire analyzer pneumatic assembly is heated.

A PrevEx analyzer was fitted on each printing press dryer to detect the possibility of solvent vapor accumulation. The PrevEx analyzers were chosen because of their "Universal Calibration" feature which prevents downtime due to re-calibration requirements.

By installing the flammability analyzers, the manufacturer was able to decrease ventilation and the associated energy costs while still staying in compliance with the NFPA code.

Clamp-on Flowmeter Locates Hard-to-Find Water Plant Leak

SITRANS FUP1010 clamp-on flowmeter

A rural water treatment plant in the Southwestern United States treats, stores, and distributes 325,00 gallons per day of water to the village it serves. The village consumes an average of 125,000 gallons a day and can store up to 1 million gallons.

The Problem

Unfortunately, the treatment plant was also losing 210,000 gallons a day due to an unknown leak.
Because of the leak, water storage was critically low at 100,000 gallons and the water service had to be temporarily shut off to half the village.

The village management hired a consultant company, at $1000.00 a day, to find the leak. The consultant worked for about a week without any luck.

The Solution

Read in the document below on how a Siemens SITRANS FUP1010 clamp-on flowmeter was used to find the leak.

Compact Coriolis Flowmeter with NTEP Custody Transfer Approval

NTEP approval for
custody transfer

When oil and gas are physically transferred from one operator to another, the term custody transfer is used to describe the transaction. It is understood as the transfer of fluid material defined by a metering device, at a given location, to another party. Custody transfer occurs at a variety of locations including from production platforms to ships, trucks, railcars, barges, and also at the final destination, such as the processing plant or refinery.

Accuracy is very important in custody transfer as both parties and instruments such as flowmeters must have approval by the organizations such as the American Petroleum Institute (API) or the National Conference on Weights and Measures (NCWM).

The National Type Evaluation Program (NTEP) is an evaluation program overseen by the National Conference on Weights and Measures (NCWM). Manufacturers who carry NTEP approval comply with local state and government regulations regarding transactions selling, purchasing, exchanging, custody transfer, or establishing the cost for services on based on weight.

Major Water Savings in Dairy Operations White Paper

Alfa Laval describes a better way to clean double-seat mixproof valves and reduce water and CIP liquid consumption even further. This involves quick and repetitive opening and closing of the seat, rather than exposing valve surfaces to CIP liquid ow for a given duration of time. This discovery was made at one of Alfa Laval’s process facilities. Alfa Laval engineers observed that, during the first fractions of a second of a cleaning cycle, the ow of CIP liquid created a high level of shear stress on the valve surfaces used less water than traditional seat lift and seat push cleaning, and increased overall cleaning efficiency.
