Description

N 1 The invention relates to the food industry (specifically, to roasting food products with movable holders) and can be used in cooking and canning in the production of roasted products from fish, meat, vegetables, etc. A device for frying products, made in the form of an i-shaped vessel, the ends of which in the upper part are connected by an overflow pipe, is known. Inside the U-shaped vessel there is a conveyor for moving the product, the vessel being filled with oil and heated in the outgoing vessel III. The disadvantages of the known device are the need to clean the oil from crumbs and particles falling out of the product to be fried (the oil is cleaned with filters, which are quickly clogged, and the device has to be stopped for parts washing), and there is a large amount of oil in the U-shaped device, which leads to high energy costs for heating the oil and its irrational use. In addition, the transport devices of the products in the u-shaped vessel are unreliable in operation and have a large mass. A device for roasting food products contains a container for heat-transfer fluid, a carrier for products made in the form of a perforated drum installed in a container with a gap, radial partitions mounted inside the drum for transporting the product, devices for loading and unloading the product 12, I Disadvantages the devices consist in the fact that the carriers of the product - the blades are located radially and ineffective when the product is stirred during frying, since the latter can t stick together and separate pieces (for example, fish) will go into a marriage, the perforated bar of the ban has closed ends, which creates additional hydraulic resistance to oil when it is squeezed through the perforation of the drum to the product to be fried, the perforated drum closed from the ends 3 2 folded in operation. In addition, the roasting process is slow because it is impossible to ensure the uniformity of the temperature of the floor. The purpose of the invention is to intensify the process of roasting products. The goal is achieved by the fact that in a device for roasting food products containing a container for a liquid heat carrier, a carrier for a product made in the form of a perforated drum mounted in a container with a gap, radial partitions mounted inside the drum for transporting the product, devices for loading and unloading the product , the ends of the drum are open, the radial partitions are perforated and scrapers are mounted at the ends of the partitions to interact with the inner surface containers, while in the lower part of the device nozzles are mounted for supplying the gas mixture to the coolant. FIG. 1 shows an apparatus for roasting food, a slit; in fig. 2 — the same side; FIG. 3 is a section view; A-A; FIG. 2j in FIG. 4 are the heating and oil circulation circuits. The device for roasting food products includes a box-shaped body 1 with an internal container 2 having a semicircular shape in cross section, inside which a perforated drum 4 is mounted on the horizontal axis of rotation 3 and does not have end walls. Between the outer perforated 5 and inner 6 surfaces, perforated radial partitions 7 are located at an acute angle to the generator of the drum 4. Between the container 2 and the outer wall of the drum 4 there is an annular gap 8, which is sealed by scrapers 9 made in the form of elastic strips (for example, from oil-resistant) rubber), attached along the profile of the radial partitions 7 to the outer surface of the drum 4. The gaps between the end walls of the container 2 and the radial partitions 7 are sealed using similar scrapers 10, p ikreplennyh on both sides with radial partitions 7.

In the lower part of the tank 2 there are nozzles 11 with nozzles for supplying the gas mixture to the annular gap 8 and the nozzle 12 for supplying oil. In the upper part of the housing 1 there are devices 13, made in the form of brushes for cleaning the scrapers 9 and 10.

Above the device is an exhaust umbrella 14 with heat exchange tubes 15 for pre-heating the vapor-gas mixture and heat exchanger 16 for pre-heating the oil with the heat of the vapor-gas mixture.

With the device, the loading unit 17 and the unloading vehicle 18 are connected with the unloading tray 19.

The cavities 20 of the drum 4 are designed to accommodate the product to be roasted, and the tray 21 to remove the pieces that accumulate during the roasting process

The drive to the drum 4 is made through the gear 22. The housing 1 of the device has a heat shield 23.

The oil heating and circulation circuits contain an oil reservoir 24 connected via pipelines to a gear pump 25 and a valve 26 with a preliminary heat exchanger 16, a remote heating device 27, a regulating valve 28, a fan 29 for injecting an air mixture through a branch pipe 11. and nozzles 30 installed in the frying zone, the control valve 31.

The device works as follows.

The raw material is transported by the conveyor of the loading unit 17 into the cavities 20 of the perforated drum 4. A gas mixture is fed into the annular gap 8 through the nozzle 1 1, and sufficient oil to fry the product, which is in the cavity, through the nozzle 12. 20 devices. When food gets into the zone of heated oil, moisture starts to form from the product, which turns into steam. The resulting vapor and hot gas mixture (e.g. air) coming through several nozzles 30 from the bottom of tank 2 forms a liquid mixture with oil. Hot vapor-gas mixture, which forms a liquid with oil

9403 .4

the mixture enters through the perforation of the radial partitions 7 in the cavity 20 and fries the food product. Giving most of the heat to the food product 5, the gas (vapor-gas) mixture with a small amount of liquid particles of oil is sucked through the exhaust hood 14, past the heat exchange tubes 15 of pre-heating the vapor-gas mixture and the heat exchanger tube 16 for oil.

On the heat exchange tubes, most of the residual steam oil suction is deposited and condenses.

5 mixtures.

The fried food product at the exit from the container 2 (due to the inclined position of the radial partitions 7) rolls onto the discharge chute 19 and then goes to the discharge conveyor 18.

The amount of incoming oil is controlled by valve 28 manually or automatically (depending on the mass and type of product entering the roasting). Breading particles and product crumbs, penetrating into the annular gap 8 or deposited on the walls of the container 2, are removed by scrapers 9 and 10 and removed from container 2. Scrapers 9 and 10 are cleaned of crumbs and small particles of the product by means of devices 13. Removed from the device surfaces particles and crumbs

removed by trays 21. 5

Thus, in the proposed device (as compared to the known ones), the need for water Q pillow is eliminated (since the product particles are continuously removed from the roasting zone by scrapers), in the cleaning system and oil settling (since the amount of oil entering the roasting is 8- 12%, i.e., the amount that the product absorbs and removes the gas-vapor mixture from the roasting zone), increases the efficiency by preheating the gas-vapor mixture and oil in heat exchangers installed at the outlet of the exhaust gas-vapor mixture The process in the frying zone is being enhanced (by providing a uniform temperature field over horizontal levels, oil turbulization and continuous mixing of the steam-oil mixture).
