Description

The utility model relates to smoking devices and can be used for hot, semi-hot, cold smoking, drying and drying of fish and meat products, and smoking of cheese.

A known installation for smoking food products (US Pat. RF No. 2032346, publ. 10.04.95), including a chamber with a pipe for supplying smoke and a gas exhaust pipe, heaters in the upper part of the chamber, a smoke generator with a heater and a hopper for sawdust. The spent flue-air mixture is discharged into the external environment through a pipeline.

A disadvantage of the known installation is:

- the lack of devices in the design for the maximum deposition of smoking components on the product, which reduces the efficiency of the installation during long smoking processes (cold smoking lasts up to 3 days). In this regard, it is advisable to use the installation mainly only for processing meat and sausage products, since the latter, in contrast to fish, can be smoked for no more than 3 hours according to technological conditions;

- imperfection of the smoke generation system that requires additional equipment (spark arrestor, smoke filter, cooler), in addition, unregulated high-temperature pyrolysis of wood arises in cigarette-type smoke generators with the release of an increased amount of carcinogenic substances, which reduces the safety of food products;

- the complexity of regulating the relative humidity of the coolant in the chamber can lead to defects in the finished product, for example, when processing fish, which reduces the versatility of the installation.

A known installation for the heat treatment of meat, sausages and fish (Pat. RF No. 2142709, publ. 20.12.99), including a thermally insulated chamber, inside of which is a casing with perforated panels. In the upper part of the chamber in the recirculation manifolds there is a fan, on the suction window of which there is an ejector connected to the casing. Inside the casing there is a nozzle for supplying coolant into the chamber and a nozzle for water injection. The air duct is made in the form of a bend with a sump and a fitting for condensate drain. Between the walls of the chamber and the casing in the upper part of the installation are electric heaters. In the rear wall of the chamber there is an opening with a pipe to remove the exhaust gas mixture. The chamber is connected to a smoke generator, at the outlet of which a spark arrester, a smoke filter and a cooler are installed. The unit is designed for heat treatment of products in a vapor-air and smoke-air environment.

The disadvantages of the known installation are:

- the complexity of manufacturing and significant metal consumption per unit area, which increases the cost of construction;

- imperfection of the smoke generation system that requires additional equipment (spark arrestor, smoke filter, cooler), in addition, unregulated high-temperature pyrolysis of wood arises in cigarette-type smoke generators with the release of an increased amount of carcinogenic substances, which reduces the safety of food products;

- the complexity of regulating the relative humidity of the coolant in the chamber can lead to defects in the finished product, for example, when processing fish, which reduces the versatility of the installation.

The technical result, which is achieved by the claimed utility model, is to create a universal smoking plant of rotary type, increasing the efficiency of the installation.

The technical result is achieved by the design features of the installation, including the use of ultrasonic generators with a frequency of 25 kHz and a power of 200 watts. The total number of generators 10 located in the inner space of the camera.

The proposed smoking installation is illustrated by the drawings shown in FIG. 1-3.

In FIG. 1 and 2 show frontal and horizontal sections of the installation, respectively, in FIG. 3 - horizontal section of the false ceiling.

The essence of the utility model is as follows.

A smoking installation, characterized in that it includes a thermally insulated vertical chamber 1 with a hermetically closing door 6, the cross section of the inner working volume of the chamber is octagonal, a shaft 5 is vertically placed in the working volume of the chamber, to which torque is transmitted from the gear motor 23, in height media with adjustable pitch fixed media for product 4 with rods 18 or grids, 10 ultrasonic generators 15 with a frequency of 25 kHz and a power of 200 watts are placed in the interior of the camera.

The unit has a compact built-in recirculation system of the drying agent, it includes the following circuit of its movement:

- the supply of the smoke-air mixture is carried out through the duct 14, in which there is a mixture of fresh air (coming through the shutter 11) and smoke (coming from the duct 12, through the shutter 13) from the smoke generator 16;

- sampling of the spent drying agent from the ducts 7 occurs through the pipe 20 in the false ceiling 9 by means of a recirculation fan 8;

- distribution and heating of the resulting mixture in the supply ducts 19 of the false ceiling 9 with the heating elements 10 installed in them (Fig. 1);

- supply of a heated working medium through the air ducts 7 to the chamber 1 and after working out again for circulation.

The installation contains:

- a system for utilizing a portion of the spent drying agent, which includes an exhaust pipe 20;

- smoke generation system - smoke generator 16, ensuring the flow of the process of pyrolysis of wood at temperatures that exclude the risk of the formation of carcinogenic substances;

- a steam generation system that includes an external steam generator (not shown in FIGS. 1-3) for humidifying the drying agent, for example, during the process of boiling the product;

- automatic control system of 22 operating modes of the installation;

- a system of ultrasonic generators 15, providing acoustic coagulation of the smoke-air mixture.

The smoking installation of the claimed design has the following advantages:

- the ability to control the distance between the media for the product, which increases the versatility of processing the product of various size-mass and species composition;

- good aerodynamic and thermal characteristics inside the chamber due to the octagonal section of the internal working volume of the chamber;

- the absence of stagnant zones in the chamber due to carriers with the product rotating on the shaft and a uniform velocity field in the chamber, which helps to improve the quality of the finished product;

- the possibility of using rods or nets, as well as their combined use

- compact design with built-in recirculation and drying agent heating systems;

- ease of maintenance and sanitation of the internal space with the width of the doorway corresponding to the working section of the chamber, as well as the external - due to the small volume of the protruding reinforcement;

- modularity, which makes it possible to assemble single-row or double-row units from several autonomous units in an adjacent way by the side or rear walls, while simultaneously processing different types of fish, as well as creating compact smoke-drying parks;

- the possibility of using simple automatic control circuits, which provides high reliability while maintaining the required heat treatment modes.

Installation works as follows.

On the control unit 22 establish the optimal mode of heat treatment of the product, include heating elements 10, recirculation 8 and exhaust fans. Upon reaching the specified degree of heating of the inner walls of the chamber 1, the recirculation fan 8 is temporarily turned off, the product 4 is loaded onto the frames 4 on rods 18 or grids. Preliminary, the frames 4 are fixed with the necessary step along the height of the shaft 5. The door 6 is tightly closed. Product 3 is processed during regulation from the control unit of the parameters of the drying agent (temperature, relative humidity, circulation speed) in automatic or manual mode. Steam for the process of cooking the product or moistening the mixture is generated by the steam generator (not shown in Fig. 1-3) and enters through the duct 14 into the chamber 1. Smoke for the smoking process from the smoke generator 16 enters through the pipe 12 into the chamber 1. At the end of the heat treatment process cooled by intensive supply of fresh air through the duct 14 and then into the chamber 1.
