Description

Food stuffing method

The invention relates to a food processing technology, in particular to a food material wrapping device and a food material wrapping method.

Because fried foods have a golden appearance, crispy taste and special aroma, they are very popular. In the process of making fried foods, the ingredients are usually wrapped in powder or slurry and then immersed in high-temperature oil for frying. The powder or slip originally wrapped on the surface of the food will become the dough on the surface of the fried food after frying, and such dough is usually quite crisp. There are already commercially available fried foods that can be stored frozen, which can be eaten only after being heated by microwaves, without waiting for lengthy cooking procedures and time, which is very convenient for the general public and the store.

At present, when such a frozen preserved fried food is produced, it can be manufactured using an automated device. After the ingredients are cut into a predetermined amount, the ingredients are transported to the sizing area by the conveyor belt to adhere the slurry, and then the foodstuffs coated with the slurry are transported to the upper powder area by the conveyor belt for processing, and the breadcrumbs are adhered to the ingredients by the viscosity provided by the slurry. surface. The breadcrumbs are then pressed down with the weight wheel to allow the breadcrumbs to more firmly bond to the surface of the foodstuff. The ingredients can then be sent to a fryer to complete the manufacture of fried foods.

However, when the sized material is processed through the powdered area, the powder still cannot completely cover the sizing material. When the ingredients are pressed by the weight wheel, the pulp at the gap between the breadcrumbs The liquid will adhere to the surface of the weight wheel. When the next weighing wheel applies pressure to the powdered material, the slurry on the surface of the weight wheel will also adhere to the powder on the surface of the powdered material, so that the surface of the food material originally wrapped in the intact powder forms an incomplete state, resulting in frying. The effect is not good.

In an embodiment, the food material wrapping device may comprise a conveying device, a sizing device, a powder falling device and a weighing wheel. The conveying device can be used to transport the food material and has a first conveying portion and a second conveying portion. The first conveying portion has a first discharge end, and the first discharge end is located above the second conveying portion. Two side walls are disposed on two sides of the second conveying portion, and a powder storage space is formed between the top surface and the two side walls of the second conveying portion. The sizing device has a slurry outlet, and the slurry outlet faces the first conveying portion and sprays the slurry toward the first conveying portion such that the slurry adheres to the surface of the food material to form a wet food. The powder dropping device has a powder discharging port, and the powder discharging port faces the second conveying portion and can be used for depositing a dry powder in the powder storage space to cover the wet food material conveyed from the first conveying portion to the powder storage space. The weight wheel is disposed above the second conveying portion. Wherein, the thickness of the dry powder deposited in the powder storage space is greater than one third of the height of each side wall of the powder storage space.

In one embodiment, a food material wrapping method comprises: conveying a food material through a first conveying portion through a sizing device, and spraying the slurry on the surface of the food material by the sizing device when the food material passes under the sizing device; Forming a wet food material, depositing a first layer of dry powder in a powder storage space of the second conveying portion, outputting the wet food material from the first conveying portion to the first layer of dry powder, and depositing the second layer of dry powder in the powder storage space of the second conveying portion Covering the wet food material on the first layer of dry powder, transporting the first layer of dry powder from the second conveying portion, the wet food material and the second layer of dry powder passing through the weight wheel, and applying pressure from the second layer of dry powder by the weight wheel .

In summary, the food material wrapping device and the food material wrapping method according to the embodiments of the present invention are suitable. Used to make a frying. Since the powder storage space can accommodate a relatively thick dry powder, the wet food material can be covered by sufficient dry powder, so that when the weight wheel presses the wet food material covered by the dry powder, the slurry does not adhere to the surface of the weight wheel. Out of the ingredients. Here, the efficiency of the food processing process can be greatly improved, and the appearance and texture of the obtained food material after being fried can be remarkably improved.

Specifically, a piece of meat (i.e., food material 6) can be placed at one end of the first conveying portion 1 and conveyed to the underside of the sizing device. The slurry is sprayed toward the first body 10 via the sizing device 3, and falls from the slurry outlet 30 to the surface of the meat piece and adhered thereto to completely cover the meat piece. Next, the meat pieces (i.e., the wet food material 7) adhered to the slurry are transported to the first discharge end 12. The excess slurry which is not adhered to the surface of the meat piece may fall from the first hole 120 at the first discharge end 12 and flow into the first recovery tank 13 located below the first conveying portion 1.

The powder falling device 4 is previously deposited about 2 to the powder storage space 203 of the second conveying portion 2 3 cm of the first layer of bread flour (ie, the first layer of dry powder 8). Further, the meat piece to which the slurry is adhered is transported from the first discharge end 12 to the first layer of bread flour in the powder storage space 203. The powder falling device 4 deposits a second layer of bread flour (i.e., the second layer of dry powder 9) of about 2 to 3 cm in the powder storage space 203 to cover the meat pieces stuck with the slurry. Here, the first layer of bread flour and the second layer of bread flour are in contact with and adhered to the slurry on the surface of the meat piece, so that the slurry is not exposed.

Next, the meat piece to which the slurry is adhered is moved below the weight wheel 5. The weight roller 5 is in contact with the second layer of bread flour, and applies a pressure of not less than 1.56 g/cm 2 to the second layer of bread flour, so that the first layer of bread flour and the second layer of bread flour are more closely adhered to On the slurry. The meat piece with the slurry and the bread flour is moved to the second hole 220, and the excess bread powder which is not adhered to the slurry falls from the second hole 220 and flows into the second recovery tank 23. Here, the processing procedure of the food material wrapping powder is completed, and the desired finished product can be obtained.
