Description

The present invention relates to the field of electrical engineering, in particular to microwave heating devices with an energy supply, and can be used in the food industry for massaging lumpy meat raw materials and heat treatment in the production of smoked products.

Vacuum meat massagers for heat treatment of meat raw materials are known, such as: FUM-2A, Ya16-FFA, PM-FVM), etc. [one]. The principle of operation of almost all meat massaging machines is the same and is based on rotation with a certain frequency of the container with the meat loaded in it. As a rule, a vacuum of 0.01 ... 0.03 MPa is created in the tank. To intensify the process of ripening meat in the ambassador, it is subjected to mechanical processing (massaging). Massaging is based on the friction of pieces of meat against each other and on the inner walls of the rotating drum and protrusions. Pieces of raw meat are loaded into the drum of the installation and include an electric motor. When the drum rotates (during the circulation of the coolant), the massing of meat raw materials occurs. During the period of mechanical impacts, filtration-diffusion transfer of curing substances occurs; in the period of rest, diffusion is carried out. The effect of mass transfer during massage is further enhanced due to the appearance of microexplosions in the tissue during mechanical action and an increase in permeability. The use of vacuum increases the effect achieved in the machining of raw materials. An increase in the intensity of distribution of curing substances (7%) is associated with the summation of the pressure fields arising from mechanical and vacuum influences. The main disadvantage is the presence of a vacuum system, which does not allow to withstand a deep vacuum in the drum, since during its rotation the system must be disconnected.

A known installation of the drum type for cooling and pressing cottage cheese in bags UPT [2]. It consists of a frame on which a tubular drum is mounted. The drum has a loading hole with sliding doors. A removable bath is installed under the drum. The hollow drive shaft is divided by a plug into two chambers. A shaft with a drum mounted on it is driven by a drive. The drum is covered by a casing with hinged lids.

An object of the invention is to develop an installation using microwave energy, which provides the intensification of the process of massaging and heat treatment of lumpy meat raw materials for the production of smoked products.

The specified technical result is achieved as follows.

Installation for salting and heat treatment of raw meat is characterized by the fact that inside a horizontally arranged cylindrical screen housing containing a drain pipe and a loading hatch, there is a tubular resonator chamber. It is made in the form of a tubular drum with internal blades and rotates in a vertical plane. The resonator chamber is assembled from pipes so that the gap between them is less than a quarter of the wavelength. One end of the resonator chamber is closed by a hollow disk, and the other is open. The hollow disk (from one end) and the annular tube (from the other end) are connected to the hollow shaft. The shaft is fixed in the bearing units and connected by means of lock nuts and gaskets to the couplings. Under the screen casing in the upper part there are grill lamps in the mesh screen. A microwave generator unit is installed at the end of the screen housing.

Installation for salting and heat treatment of meat raw materials (Fig.1, 2) contains in a cylindrical screen housing 1 a tubular resonator chamber 3, from the end of which a radiator is directed from the generator unit 5 with a magnetron. The hollow shaft 7 is laid through the central axis of the tubular resonator chamber 3. In this case, the shaft is rigidly connected to the end hollow disk 15 and the annular tube 6 of the resonator chamber 3. The shaft 7 is installed in the bearing assembly 8. The tubular resonator chamber 3 rotates from the gear motor. Moreover, the generator unit 5 and the loading hatch 12 are located on the open end of the resonator chamber 3. At the bottom of the cylindrical screen housing 1 there is a drain pipe 14. On the inside, the resonator chamber contains blades 4. One end of the tubular resonator chamber is completely closed by a hollow disk 15, and the other the end is looped by a pipe 6. Under the cylindrical screen body 1, grill lamps 2 are installed. The curing brine 16 and lump meat 17 are loaded through the loading hatch 12. Moreover, through the slots 13 between the pipes of the resonator chamber 3 p saline brine 16 seeps to the bottom of the screen housing 1 and fills part of the meat raw material 17 located in the chamber 3. Each bearing assembly 8 includes a clutch 11, a lock nut 10, a gasket 9 and a bearing assembly 8. There is a plug 18 in the middle of the hollow shaft 4.

Installation for salting and heat treatment of raw meat is as follows. Raw meat 17 and curing brine 16 are loaded through the loading hatch 12. Next, the hatch is closed 12. The coolant is fed into the pipes of the resonator chamber 3 through the coupling 11. The coolant (hot water) from the pipeline passes through the coupling 11 into the right chamber, as in the hollow shaft 7 there is a plug 18. Then, bypassing the tubular resonator chamber 3, enters the left chamber and returns through the pipe to the network pipeline. The lock nut 10 and the gasket 9 to the bearing assembly 8 limit the flow of coolant.

At the same time include a gear motor that rotates the shaft 7 with the resonator chamber 3 at a speed less than critical. The process of massaging lumpy meat raw materials 17 begins, while due to the blades 4, the pieces of meat 17 rise to a certain height and fall, that is, a filtration-diffusion process is underway. Curing brine 16 is absorbed into the tissue of meat raw materials 17. At the same time turn on the microwave generator unit 5 for low power. Due to the heat from the pipes and the influence of the microwave electromagnetic field, the effect of mass transfer during massaging of meat raw materials is further enhanced. Curing materials 16 are mainly redistributed due to exposure to EMFHF. With further exposure in the ambassador, the diffusion transfer is slow, but still faster than in the meat raw material, which was not exposed to EMFHF. After massaging the raw meat, the remaining brine is drained through the drain pipe 14. The microwave generator 5 is turned on at full power, the grill lamps 2 are turned on, and a steam-water mixture is circulated through the pipes of the resonator chamber 3. In this mode, the product is cooked and smoked. Next, turn off the microwave generator 5, change the coolant in the pipes to a coolant (tap water or cooling brine). In this case, the finished product is cooled, after which the rotation of the resonator chamber is stopped, turning off the gear motor. Open the hatch 12 and unload the finished smoked product.
