What is the difference between vacuum fryers and atmospheric fryers?

Fried food is a kind of processing technology commonly used in deep processing of food. At present, there are many kinds of food frying technology. At present, the two technologies commonly used are atmospheric frying and vacuum frying. Let's analyze it in detail.

First, the working principle is different

Atmospheric pressure frying machine is a kind of frying technology commonly used in the food processing industry. The atmospheric pressure frying machine works when the internal pressure is standard atmospheric pressure. Its advantage is the processing is convenient, through atmospheric Fried processed food good crispness, good flavor, and vacuum frying machine is at work in the case of a relative lack of oxygen for processing of Fried, its absolute pressure below atmospheric pressure, the food processing by adopting the technique can greatly limit retained the flavor and nutritional ingredients of raw material, can prevent the oxidation of edible oils and fats.

Second, advantages and disadvantages are different

Atmospheric pressure frying machine is often used for food Fried, such as we usually eat fried cakes and fried bread are using this atmospheric pressure frying machine for frying. The atmospheric pressure frying machine in the process of food frying can not maintain the nutrition of food, but also cause the loss of natural color of food. Vacuum frying machine is on the contrary, it can maintain the nutrition and color of food to a large extent. For example, a very popular snack food like fruit and vegetable crisps is fried by this kind of vacuum framer.

Three, frying temperature is different

Compared with normal pressure frying, vacuum frying machine can reduce the evaporation temperature of water in the material, the heat consumption is relatively small, the frying temperature is greatly reduced, it can reduce the loss of heat-sensitive ingredients such as vitamins in food, which is conducive to maintaining the nutritional composition of food and avoiding food coking.

In the choice of vacuum frying machine and atmospheric frying machine, we need to frying according to the requirements of the actual products, and then make the corresponding choice. Only when all aspects meet the requirements, is it more suitable!
