Description

1The invention relates to a device for the heat treatment of food products, namely for fish storage.

Devices are known for smoking, products, and for example fish consisting of, tunneled, divided into zones of drying, smoked and smoked, cooling chambers,: passing through OjCO through, tunnel, and. cooling conveyor chamber. with a traction chain for moving, bodies installed with the product, c. zone. for circulation of med. fumes, smoke generator, steam humidifier and ejector,. supply of a smoke-air mixture, air heater, for heating the air and for the system of automatic control of temperature, humidity and density of air and smoke.

However, in the faithful devices; the temperature is not uniform, which results in a finished product that is not uniform in moisture, color and taste. To ensure uniform temperature across the entire tunnel length and improve the quality of the finished product, the proposed device is equipped with additional heaters that are sequentially placed in the upper and the lower part of the tunnel for staged air heating.

Nor, with and are equipped with a time relay and limit switches.

N. FIG. 1 schematically shows the proposed device, a longitudinal section; in fig. 2 - the same plan view; in fig. 3 - the same cross section; in fig. 4 is a diagram of the supply of smoke to the zone, smoked.

The device consists of a tunnel /, divided into zones of drying, boiling and smoked,

cooling chambers 2 passed through tunnel 1 and chamber 2 at the top. part of the monorail track 3, and at the bottom - a conveyor with a pulling chain 4; on which fortifications are strengthened. moving carts 5 with the product.

Zyns, tunnel, / and cooling chamber 2 are divided by. the length of the compartments corresponding to the size of the cart. Fingers are mounted on the conveyor chain 4, ensuring that the conveyor stops after moving the cart from one compartment to another.

The zones of drying and welding are equipped with axial fans respectively. 6 and 7. The smoked zone is connected by a duct system with a smoke generator 8 and an ejector 9

for supplying a smoke-air mixture blown by the fan 10.

At the bottom, on both sides of the tunnel / and directly on it, the heaters 11 are installed on a step-by-step basis. A fan / 2 is mounted to the cooling chamber 2 for supplying cooling air and a plate heater 13 for heating the air, if necessary,

To ensure that the air in the tunnel only moves in a vertical direction, shields are mounted on the sides of the carts. A carriage with rollers 14 is mounted in the upper part of the trolley for moving the trolley along a mono, rail track 5. In the lower part of the trolley there are removable pallets 15 for directing air flow and collecting padants and broth. To regulate the humidity of the air, gates 16 are provided in the device.

The device works as follows.

Fish strung on rods and laid on frames are loaded onto trolleys 5, which are moved in a tunnel / along a monorail 5 by means of a circuit 4.

The tunnel is broken by the length of thirteen of the sections. In it, at the same time, the same number of carriages are placed. In the first four compartments, as the carts move, the fish is dried and boiled.

Circulation of air in these compartments is provided by an axial fan 6. Fresh air is mixed with the exhaust air from the fourth compartment and is supplied by fan 6 partly to the heater 11 installed in the tunnel, and partly to section I. is emitted into the atmosphere.

The air, heated in the heater // to 100 ° C, passes through compartment II from top to bottom, is humidified and cooled, while heating the fish. Then the same air is again heated in the heaters 11, located on both sides of the tunnel in its lower part up to 120 ° C and passes through compartment IV, where the fish is boiled upwards.

In compartments VI, VII, VIII, the fish is dried and partially smoked. Here, the circulation of fresh air mixed with the smoke exhausted in the smoking zone is provided by the fan 7.

The mixture, heated in the heater 11, flows from top to bottom through compartment VI. Then again, heating up in the heaters 11, located on both sides of the tunnel, passes through the VIP bay from bottom to top. The gas temperature during smoking of small fish is maintained from 100 to 110 ° C.

The actual smoking takes place in compartments X, XI and XII, through which smoke passes from the smoke generator 8, which is preheated in the heater / 7 to 90-100 ° C.

Through this zone, the smoke, the passage at a speed not exceeding 0.5 m / s, is mixed with air coming from compartment VIII, diluted with fresh air, partially enters the heater 11 and then into compartment VI, and partially emitted into the atmosphere. Compartment XIII tunnel serves as a shutter.

Temperature adjustment is made by throttling the heating

couple. Temperature and humidity conditions in the tunnel depends on the type of raw material.

From the tunnel, the fish enters the cooling chamber 2, divided into three compartments. Here the fish is blown with cold air at a temperature of + 20 ° C supplied by fan 12.

To control the duration of the process of heat treatment of fish, the device uses a CEP system with a time relay, through which the time of the conveyor is determined, determined by the quality of the fish to be processed in accordance with the requirements of the technological regime. The temperature and humidity conditions in the tunnel are recorded on the console.

control with recording devices.
