Screw extruder Fry snacks machinery,different process ,different quality

The conventional wheat flour snacks produced by twins screw food extruder and the starch snacks pellets produced by the single screw extruder, need to be fried at high temperature to achieve the final maturation and complete processing. High temperature frying process is a conventional way of food puffing. In the whole food industry, high temperature frying and high temperature baking are two types of common processing. After all, extrusion processing, even though popular now, is only relatively limited in the starch raw materials and some protein raw materials very small presence.


The high temperature frying, beside making the material mature, can also achieve a certain degree of sterilization and the overall drainage effect of food particles, the result of oil squeezing water is that the food taste better, and crispy. In fact, this is the main reason for the enduring popularity of fried food.

Of course, in the frying processing, based on the determination of raw materials and technology, the quality of oil plays a great role in the final taste and shelf life of the food. Therefore, the quality control of oil has become a very important evaluation standard to determine the quality of food.


After production a day, the used oil needs to be stored in oil tanks. It is impossible to directly waste the clean but used oil, it will be gradually used in the production process in next day. So, the question is: the next day's production, adding the used oil into fryer machinery directly, and then gradually add new oil during production to keep enough oil in fryer? Or, add new oil directly, gradually adding old oil into fryer? This is a question for all the snacks producer.


In fact, no matter old oil or new oil, eventually need to be consumed, it is impossible to waste, after all, this is the production of raw materials, belong to the cost, related to profit.


So, on the whole, whether you directly add the new oil the next day or add the old oil, oil will quickly enter the consumer's mouth with the snacks together soonest. But the two different treatments, its have a big effecting on the quality, the taste, the shelf life of the puffed food.


The details can reflect the producer's sense of social responsibility and conscience. We need to use law and conscience together to keep the food hygiene.


All of us hope the smell of food around us, is truly hygienic and clean.
