Abstract

The invention relates to refrigeration engineering, and specifically to devices for freezing foodstuffs in a stream of cold air. The purpose of the invention is to intensify the freezing process and reduce energy consumption. The fans 2 blow the air through the cooling batteries, where it cools, dries and enters the container 7 with the product installed on the conveyor rollers 6. The heat insulated casing is divided by length by pivoting partitions 5 into separate compartments 4. The presence of pivoting partitions 5 creates a closed loop for movement air, eliminating the possibility of its flow, mine containers 7 with the product and ensuring uniform air flow. The lifting of the partition 5 is carried out due to its rotation around the axis 8 by the container 7 with the product during its movement. When the container 7 is advanced into the next compartment 4, a cooling system is turned on therein, and the fans 2 and the cooling batteries are activated from the moment of loading of the corresponding compartment 4, which saves a lot of energy. The unloading can be carried out reversibly (both ways). 2 Il.

Description

The invention relates to refrigeration engineering, in particular, to devices for freezing foodstuffs in a stream of cold air.

The purpose of the invention is to intensify the freezing process and reduce energy consumption.

FIG. 1 schematically shows the proposed device, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

The next container 7 with the product enters the housing 1 by switching on the drive 9 of the two blocks of conveyors 6, while the container 7 with the product already in the housing 1 opens the partition 5 by rotating it and thereby allowing the container 7 to move with the product in the next section 4.

The process is repeated until the device is fully loaded. In this case, the fans 2, including the freezing food 10, are in operation since the loading of the products, contain a heat-insulated casing 1, a cooling system including fans 2 and cooling batteries 3, located in compartments 4 formed by vertical partitions 5 arranged along the length of housing 1 and attached to the ceiling of housing 1. In addition, the device comprises a roller conveyor 6 for moving the containers 7 with the product.

4, which significantly saves energy.

The unloading of containers 7 with the product can be carried out reversibly (in both directions) depending on the layout of the room where the device is installed.

The implementation of the cooling system and conveyors from separate units installed in each compartment and having an individual drive ensures reduction

Each partition 5 in the area above 20 electricity costs due to their subsequent transporter 6 has an axis 8 of rotation, which is included in the work.

laid over the conveyor. The cooling system and the conveyor 6 consist of separate units installed in each compartment 4 and having an individual drive 9.

The food freezing apparatus operates as follows.

The fans 2 blow the air through the cooling batteries 3, where it is cooled and dried, and through ducts (not shown) supply it to the containers 7 with the frozen product. The proposed freezing device allows to intensify the freezing process, ensuring uniform air flow and eliminating its flow into compartments not filled with containers with the product.

Invention Formula thirty living. The containers 7 are mounted (for example, by an electric forklift) on the rollers of the conveyor 6. A device for freezing foodstuffs, comprising a heat insulated casing, a cooling system including fans and cooling batteries, a roller conveyor for moving the loading and unloading devices 35 containers with products characterized by The sloping elements are placed outside the insulated housing 1. The presence of pivoting partitions 5 creates a closed loop for air movement, eliminating the possibility of air flowing over, passing the product containers 7, and ensuring uniform air flow. The rotation of the partition 5 is carried out due to its lifting by the container 7 with the product as it moves along the conveyor 6, driven by the drive 9. 40 that, in order to intensify the freezing process and reduce energy consumption, the chamber is equipped with vertical partitions arranged along the length of the chamber and attached to the ceiling of the housing to divide it into compartments, each partition having an axis of rotation in the area above the conveyor belt, and the cooling system and conveyors consist from separate units installed in each compartment and having an individual drive. The next container 7 with the product enters the housing 1 by switching on the drive 9 of the two blocks of conveyors 6, while the container 7 with the product already in the housing 1 opens the partition 5 by rotating it and thereby allowing the container 7 to move with the product in the next section 4. The process is repeated until the device is fully loaded. In this case, the fans 2 are switched on from the moment of loading of the compartment 4, which makes it possible to significantly save electricity. The unloading of containers 7 with the product can be carried out reversibly (in both directions) depending on the layout of the room where the device is installed. The implementation of the cooling system and conveyors from separate units installed in each compartment and having an individual drive ensures reduction electricity costs due to their sequential inclusion in the work. The proposed freezing device allows to intensify the freezing process, ensuring the uniformity of the air flow and excluding its flow into the compartments that are not filled with containers with the product. Invention Formula A device for freezing foodstuffs, comprising a heat-insulated housing, a cooling system including fans and cooling batteries, a roller conveyor for moving containers with products characterized in Tiners with products, characterized by that, in order to intensify the freezing process and reduce energy consumption, the chamber is equipped with vertical partitions arranged along the length of the chamber and attached to the ceiling of the housing to divide it into compartments, each partition having an axis of rotation in the area above the conveyor belt, and the cooling system and conveyors consist from separate units installed in each compartment and having an individual drive. 5 A-A FIG. 2
