Description

Automatic film coating device for ham film coating process

Technical Field

The invention relates to the field of food surface coating, in particular to an automatic coating device for a ham coating process.

Background

Ham is a cured meat product, has good color, aroma and taste, rich nutrition and long-term storage, and is deeply loved by people. The traditional Chinese ham is processed and produced under natural conditions, is greatly influenced by natural climate, and has the problems of unstable product quality, low yield and the like; in order to prevent the ham from being rotten in the processing process, the salt content of the ham is generally higher, the flavor is influenced, and the ham is not beneficial to human health. Therefore, the development of the modern production process of the ham is an urgent problem to be solved.

In the modern production process of the ham, a protective film is required to cover the surface of the ham after the pickling, so that the ham is prevented from mildewing in the fermentation and aroma raising processes, and the quality and the edible safety of the ham are ensured. At present, the coating method mainly comprises three methods: dip dyeing, spray coating and brush coating. The dip-dyeing method is suitable for liquid coating with good fluidity, and has poor applicability to solid-liquid mixtures with poor fluidity and high viscosity; the spraying method is suitable for the paint with medium viscosity, and the paint is dispersed by a pneumatic ejector and then sprayed on the surface of an object to be coated; the brush coating method is suitable for coating with higher viscosity, and the coating is brushed by using a brush coating tool to contact with the surface of a coated object.

The prior art discloses a safe automatic film coating machine for penaeus vannamei boone, in order to coat preservative on two sides of the penaeus vannamei boone, a brush roller is arranged in the film coating machine, the brush roller rotating anticlockwise is used for turning over the penaeus vannamei boone coated with preservative solution and then conveying the penaeus vannamei boone to the lower part of another nozzle for secondary spraying, so that the two sides of the penaeus vannamei boone can be sprayed with the preservative solution. However, the turning function of the brush roller of the device is unstable and is not suitable for spraying large and heavy objects.

Because the upper surface and the lower surface adopt different film coating modes, the brush roller only can act on the upper surface, the film coating amount and the uniformity of the upper surface and the lower surface cannot be kept consistent, and the four sides of the pork are also out of the film coating range, so that the pork cannot be effectively protected.

Modern ham processing adopts suspension type, temperature and humidity control's fermentation process, and whole production process all goes on in the fermentation vat, and above-mentioned two types of coating devices have adopted the conveyer belt to carry the mode that the material carries out the film, and the problem that exists is: on one hand, the food is contacted with the outside to increase the pollution risk, and the original form of the food can be damaged by the contact type coating film, even the mechanical damage is caused; on the other hand, the device has no operation space in the fermentation chamber fully covered with the meat hanging bracket because the machine body is larger.
