Dry salt pickling machine
Technical Field
The invention relates to the field of food processing equipment, in particular to a dry salt pickling machine.
Background
The pickled product has unique flavor and taste and has great domestic and foreign demand market.
The basic process of food pickling comprises a salting process and a curing process of pickled products, wherein the salting process means that raw food raw materials are in contact with solid table salt or are soaked in table salt water, the table salt permeates into the raw materials, and simultaneously, water in the raw materials gradually seeps out under the action of osmotic pressure, so that the water activity of the raw materials is reduced. Generally, the rate of change is primarily affected by the amount of salt used, with the greater the amount of salt, the greater the rate and amount of permeation. After the raw materials are salted for a period of time, the concentrations of the salt inside and outside the raw materials are balanced, and the mutual permeation between the salt and the water is stopped, so that the salting balance is achieved. The maturation stage refers to the breakdown of proteins into short peptides, free amino acids and amines by endogenous enzymes, while soluble components produced by the muscle are eluted. These material components affect not only the proliferation of microorganisms but also the flavor of the cured product. For example, during the salting process of salted fish, free water is firstly exuded, and when the salt solution destroys the protein colloid of the fish tissue or the endogenous protease in the fish body breaks the protein water, part of the bound water originally bound on the protein molecule becomes free water and also exudes to the outside of the body.
The dry pickling method is a method of directly applying a proper amount of crystalline salt (dry salt) to the surface of a raw food material to pickle the raw food material. In the dry pickling process, under the action of osmotic pressure and moisture absorption of salt, the salt can absorb water in the raw food material to form a salt solution (brine), and the pickling agent permeates into the raw food material through diffusion in the brine. However, the salt water produced by the dry pickling method is slowly oozed out by the raw material tissue fluid, and the salt is slowly permeated into the raw food material body at the beginning, so that the time required for pickling is long.
The dry pickling method is simple and convenient to operate; the raw food raw material dehydration efficiency is high, and a large amount of salt can absorb heat when dissolved, and the temperature of the fish body can be reduced, so that the food pickled by the dry salt method is not easy to rot in the salting process.
However, the formation of the brine by the dry pickling method requires a certain time, the contact area of the raw food material on the upper part with the air is large, fat oxidation easily occurs, and in the presence of metal ions, the oxidation of the fat is accelerated, and the phenomenon of oil burning is easily caused. When a large container is used for salting, the melting time of dry salt on the upper layer in the container is longer than that of the dry salt on the bottom layer, the salting degrees of raw food materials on the upper layer and the lower layer cannot be uniform due to the pressure difference in the container, and along with the prolonging of the salting time, the concentration of liquid on the upper layer in the container is lower than that of the liquid on the lower layer in the container, so that the salting is not uniform, and the salting time of the raw food materials on the lower layer is earlier than that of the raw food materials on the upper layer; the dry pickling method also has disadvantages that uneven salt penetration tends to occur when the salt is unevenly distributed, spots tend to remain on raw food materials when the salt is penetrated, and the raw food materials are deteriorated in appearance due to strong dehydration. The product value is reduced; if the food materials in the container are periodically and manually turned over in order to be evenly cured, a great deal of labor and time are consumed, and putrefying bacteria are easily bred. At present, the mechanization degree of the enterprise of the dry pickling method is not high.
