Vacuum frying technology is a method of frying fruits and vegetables at low temperature using a vacuum fryer. A vacuum frying machine can help prevent nutrient loss, which is common when cooking or frying foods at high temperatures. Food color, consistency and flavor are well preserved. This frying process keeps food longer, contains less oil and is healthier than other types of fried foods.
It is carried out under subatmospheric pressure. Vacuum frying changes the color, appearance, texture and composition of a product, making it more appealing to consumers. Fruits and vegetables have been recognized as having broad applicability to the technology.
The vacuum fryer is mainly composed of vacuum frying tank, oil heating system, vacuum system, oil storage and replenishment system, pneumatic system, automatic deoiling system and other systems. It is a frying machine that integrates frying, deoiling, dehydration and oil filtration to process fruit and vegetable products, seafood, meat products, etc. under vacuum.
Some vacuum frying systems incorporate a method of centrifuging the frying sample within the frying chamber. In the case of vacuum frying, this problem is exacerbated by the pressurization step, which causes a rapid increase in pressure in the pore space, forcing most of the surface oil into the product pore space. Therefore, vacuum frying requires a degreasing mechanism to reduce excessive oil absorption on the product surface.
With the improvement of living standards, nutrition, convenience, safety and greenness are the current trends in the development of food production. Consumers' demand for snack food is no longer satisfied with the more basic consumer needs such as good taste, hygiene and high packaging grade. The functional benefits and spiritual enjoyment of the vacuum fryer fruit and vegetable chips products just meet the needs of consumers.
