Development history and type analysis of vacuum frying machine
In recent years, called a fruit and vegetable chips was welcomed by consumers in particular, fruit and vegetable products deep processing into fruit and vegetable chips not only avoids the problem of fruit and vegetable storage life short, but also brings the new consumers experience, and this kind of fruit and vegetable chips are made of fruit and vegetable vacuum frying machine for processing, then the vacuum frying machine is how to develop? What are the commonly used models of it? Let's analyze it together.
I. Development history
When it comes to the development of vacuum frying machine, we have to mention vacuum frying technology. In the late 1960s and early 1970s, vacuum frying technology has emerged. After the 1980s, this technology has gained rapid development, and there are more and more wide applications.
Two, commonly used models
1, vacuum frying machine
Vacuum frying, as the name suggests, is to fry in a vacuum. In a vacuum, the gap between fruits and vegetables is expanded, the water is rapidly gasified, expanded, and the puffed effect is good. The fried products are crispy and delicious.
2, low temperature vacuum frying
By lowering the boiling point of frying oil and water to a lower temperature than the atmosphere, the water in the fried product will evaporate quickly. For example, the temperature of the oil under normal pressure needs to be 150-220 degrees, and the oil temperature is 80-85 degrees when the vacuum degree is 93.3 kPa. Therefore, vacuum frying machine is also called low temperature vacuum frying machine. The equipment is widely used in processing fruit and vegetable chips.
Three, matters needing attention
Cooking food is easy, but making it taste good is the core technology of vacuum fryers. This is largely related to the oil temperature of vacuum frying. How to control the oil temperature is specifically reflected in the following aspects.
1, vacuum frying machine is to use the temperature controller to schedule different gears, and then control the frying product oil temperature of the concave and convex, in the circuit
When the temperature reaches its own temperature limit, the limiting temperature rise will be automatically disconnected. When the temperature drops below the temperature limit, the temperature limiter can automatically connect the circuit and make the heating equipment continue to work.
2. Another temperature control device of the vacuum frying machine is the fuse. When the temperature reaches the temperature limit, the fuse will burn after it can maintain the personal and property protection of the equipment and the operator.
Vacuum frying machine, in line with the modern concept of consumers for health food after frying oil less, because of that, so the vacuum frying machine once into the market, also is the consistent good opinion of each big enterprise, the current vacuum frying machine related technical staff is working on the related research and equipment upgrade, in the coming days, there will be more intelligent vacuum frying machine appeared in front of us!
