A plate-and-frame heat exchanger; also widely used in food-processing industry. Heat exchangers:Geometries 5/74 /1 2 tube pass heat exchanger is operated with hot fluid in/out temperatures T1 = 182°C, Most common are (low pressure) steam-heated vertical-tube evaporators, with the boiling liquid inside the tubes under a moderate vacuum
FOOD PROCESSING - Engineering solutions for heating Heat Source:Steam, Hot Water & Exhaust Gas Capacity:50 250 TR BRINE TEMPERATURE:-5 to -25 O C. Heat energy available in the form of. Dry saturated steam (0.5 3.5 bar.g) Dry saturated steam (5.0 10.5 bar.g) Low temperature hot water (90 150 O C) High temperature hot water (150 180 O C) Exhaust gases (300 600 O C)
The conventional method for heating products to ultra-high temperatures has been to use indirect heating such as 1) plate and frame heat exchangers, 2) tubular-type heat exchangers such as shell and tube, or 3) scraped surface heat exchangers. The other current method for UHT production is steam infusion. The goal of the equipment manufacturer
Pasteurization Systems - API Heat TransferA product passing through a high temperature short time heating system is pre-heated in the heat recovery section, it is then brought to pasteurization temperature in the heating section, held for prescribed time in the holding tube before the temperature is lowered in the heat recovery section, and finally cooled to the packaging or storing
2007). Pasteurization could be done by heating the milk stream using heating equipment such as heat exchanger, or heating the already packaged milk (in-container pasteurization). In-container pasteurization usually utilize hot water bath or steam / hot water spray. Hot
Solved:Heat Exchanger For Food Pasteurization:Orange Jui Heat Exchanger for food pasteurization:Orange juice, flowing at a rate of 3600 kg per hr, is to be pasteurized by heating it from 10 C to 80 C in a simple shell and tube heat exchanger. Hot water enters at 90 C and flow counter-currently to the orange juice, leaving at 34 C.
A shell and tube heat exchanger consists of a bundle of tubes enclosed in a cylindrical shell. The ends of the tubes are fitted into tube sheets, which separate the primary and the secondary fluids. Where condensing steam is used as the heating medium, the heat exchanger is usually horizontal with condensation taking place inside the tubes.
Steam Heating Process - Load Calculating
Changing Product Temperature - Heating Up The Product with Steam
UHT Pasteurization involves a preheating process, followed by exposure to high temperatures of 130-150 °C for 0.51.0 second. During UHT Pasteurization:The product is pumped through an air removal system to the heat exchanger. After heating the product, it passes through the holding tube where it receives the required time-temperature effect
Steam generator - Shell and tube heat exchangers - QuiriThe steam generator, which is a multitubular heat exchanger, of Quiri thermal design, ensures the production of saturated steam by condensing superheated steam. The superheated steam comes from the steam extraction of the turbine. The heating steam supply pressure (primary side) to the steam generator is controlled to maintain constant steam
