With the improvement of people's living standards, food hygiene standards have become more and more stringent. Our
Plate Heat Exchanger industry has increasingly stringent and mechanized food hygiene requirements. From the previous artificial cooling to the current complete mechanization, this is the development demand of the times.
In the beverage production line in the food industry, the main functions of the supporting plate heat exchanger are: refrigeration, heating, volatilization, and cooling.
The most common applications are pasteurization and ultra-low temperature filling.
As long as it is about the heat exchange between water-water and steam-water, it is inseparable from the existence of plate heat exchangers.
In plate heat exchangers used in the food industry, special attention should be paid to the material of each part of the plate heat exchanger. Including the clamping plate shell, heat exchange plate, gasket, bolts, etc., stainless steel should be considered first.
Let's take a look at the requirements and applications of plate heat exchangers in the pasteurization process:
The plate heat exchanger used in the pasteurization process is mostly a detachable plate heat exchanger, and the corrugation of the heat exchange plate is herringbone corrugation and horizontal corrugation.
Sealing strip specifications must comply with FDA standards, convenient maintenance, high quality standards, widely used in the sterilization of fresh milk in the dairy industry and cooling of dairy products, and can also be used for fruit juice, vinegar, drinks, soy sauce, wine, etc. It is an ideal sterilization heat exchange equipment for heating and cooling in the field.
The difference between the plate heat exchanger used in the sterilization process and the heat exchanger used in the chemical industry and other less demanding plate heat exchangers is believed to be clear to everyone.
From the outside, they all have the same structure and style, but there must be gaps in materials and craftsmanship.
Gaskets for food, bolts and connecting rods of various parts, including the clamping plate of the outer frame are also required. No matter whether it is a food company or a plate heat exchanger manufacturer, it cannot be shoddy, and it must be cautious.
In the food industry, the application of plate heat exchangers in hot water boilers is also more common.
The hot water boiler is generally installed at the end of the production line in the working condition, so as to recover the steam condensate discharged from the boiler.
Its value is to recover the heat of the steam condensate, heat the ordinary make-up water, make the boiler make-up water temperature higher than normal, shorten the time required for the water to reach the boiling point to generate gas, and reduce the fuel consumption required for the raw make-up water.
Plate heat exchangers for hot water boilers are not only used in food, but also in industries such as chemical industry, light industry, textile, rubber, metallurgy, electric power, machinery, etc., where hot water boilers can be recycled and reused. Exchanger for heat exchange, heating, cooling and other purposes.
