Description
Technical Field
The utility model relates to a food multilayer chain transmission cooling device.
Background
At present, in food production industries such as chocolate, energy bars, sugar bars and the like, food is generally required to be cooled and solidified after being poured, and currently, common cooling and solidifying equipment is a multilayer chain transmission cooling device, and as shown in fig. 1, the mechanism mainly comprises a cooling box body 1, and a multilayer chain transmission mechanism 2 and a refrigerating mechanism which are arranged in the cooling box body 1. The multilayer chain transmission mechanism 2 drives the chain 2b arranged in a shape like the Chinese character 'ji' to run through a plurality of groups of driving chain wheels 2a which are longitudinally designed, so that the conveying plate 3 used for conveying food on the chain 2b can move along the route like the Chinese character 'ji', and the cooling path is prolonged. The switching of the conveyor plate 3 between the upper and lower chain levels is then performed by means of a gear lifting mechanism (not shown). The gear lifting mechanism adopts two gears with the same specification which are positioned at the alternate positions of the chain layers and are arranged in a diagonally staggered manner, and the lifting or the descending of the conveying plate 3 between the chain layers is realized by matching with the clamping columns which are diagonally arranged on the conveying plate 3.
As shown in fig. 1, the refrigeration mechanism is disposed at a position below one side of the multi-layer chain transmission mechanism 2, and the known refrigeration mechanism mainly includes an axial flow fan 4, an evaporator 5 and an air guide cover 6, an air outlet 4a of the axial flow fan 4 faces away from the multi-layer chain transmission mechanism 2, the evaporator 5 is disposed between the axial flow fan 4 and the multi-layer chain transmission mechanism 2, and an outlet thereof is connected with an air inlet 4b of the axial flow fan 4 through the air guide cover 6. The wall surface facing the air outlet 4a of the axial flow fan 4 in the cooling box body 1 is provided with an air return cover 7. Under the action of the axial flow fan 4, the air in the cooling box body 1 is cooled by the evaporator 5 and then output to form cooling air flow, the cooling air flow is guided by the air return housing 7 and rebounded to blow to the upper part of the multilayer chain transmission mechanism 2, and then sequentially passes through a cooling channel C formed between the chain layer in the multilayer chain wheel driving mechanism 2 and the chain layer to cool food, and then returns to the evaporator 5 from the lower part of the multilayer chain wheel driving mechanism 2 to form circulation.
However, during long-term use, we have found that the refrigeration mechanism described above exposes the following problems:
1) because of the inherent problem of the working mode of the axial flow fan 4, the mechanism excessively depends on the action of the internal return air housing 7 to complete the circulation of cooling airflow, but the energy of the cooling airflow is greatly lost after the guiding and rebounding of the return air housing 7, so that the force of the cooling airflow entering the multi-layer chain transmission mechanism 2 is insufficient, and finally, the integral cooling efficiency of the device is not high and the effect is not good;
2) in order to better guide the cooling airflow generated by the cooling mechanism to enter the multi-layer chain transmission mechanism 2, an air outlet guide cover 8 is often required to be installed at a position close to the upper part of the multi-layer chain transmission mechanism 2, and the cooling airflow rebounded by the air return cover 7 is gathered and guided to flow into the multi-layer chain transmission mechanism 2, so that the component and production cost is increased, and the energy of the cooling airflow is further lost.
3) Axial fan 4 and evaporimeter 5 adopt transversely to arrange, comparatively occupy space for not only make the inside wind channel length of cooling box 1 elongated, increase the energy loss of cooling air current, also extravagant material has increased the manufacturing cost of cooling box 1 moreover.
Disclosure of Invention
The utility model discloses the purpose is: aiming at the defects of the prior art mentioned in the background art, the food multilayer chain transmission cooling device is higher in cooling efficiency and better in effect, and is simpler in structure and lower in manufacturing cost.
The technical scheme of the utility model is that: the utility model provides a food multilayer chain transmission cooling device, include the cooling box and locate multilayer chain drive mechanism and the refrigeration mechanism in the cooling box, refrigeration mechanism is located multilayer chain drive mechanism one side, its characterized in that refrigeration mechanism includes centrifugal fan, evaporimeter and wind scooper, evaporimeter and centrifugal fan adopt fixed knot to construct and fix in the cooling box, and centrifugal fan is located the top of evaporimeter, be equipped with the return air passageway between the entry of evaporimeter and the multilayer chain drive mechanism of one side, and the export of evaporimeter links to each other with the axial air intake of centrifugal fan through the wind scooper, and centrifugal fan's air outlet is then towards the multilayer chain drive mechanism of one side.
Furthermore, the utility model discloses in the cooling box in be equipped with the support frame between multilayer chain drive mechanism and the refrigeration mechanism, this support frame and the cooling box internal wall face relative with it are fixed with first baffle and the second baffle that arranges from bottom to top together, the evaporimeter is fixed on first baffle, centrifugal fan is fixed on the second baffle; the air guide cover passes through a groove formed in the second partition plate and is connected with an axial air inlet of the centrifugal fan; the air return channel is formed between the first partition plate and the bottom of the cooling box body, and the inlet of the evaporator is communicated with the air return channel through an opening formed in the first partition plate; and an air outlet channel for connecting the air outlet of the centrifugal fan and the multi-layer chain transmission mechanism is formed between the second partition plate and the top of the cooling box body.
Furthermore, in the present invention, the vertical height from the bottom of the cooling box to the first partition is H1, and the vertical height from the top of the cooling box to the second partition is H2, H2> H1. The design makes the bore of air-out passageway be greater than the bore of return air passageway like this, and the effect is the output of reinforcing cooling air and controls the backward flow, and the purpose ensures that cooling air can act on in multilayer chain drive for a longer time, implements abundant cooling to food, helps improving cooling efficiency and effect. On the contrary, if the diameter of the return air channel is designed to be too large, the dissipation of the cooling air flow is accelerated, and if the diameters of the outlet channel and the return air channel are designed to be consistent, the advantage is not formed.
It should be pointed out that the utility model discloses in do not make structural improvement to multilayer chain drive mechanism, so it refers to prior art completely. Like prior art, the utility model provides a multilayer chain drive includes the multiunit driving sprocket drive through longitudinal arrangement and is the chain that "oneself" font was arranged, and the chain is used for the conveying board that the food was loaded in the transmission.

In practice, it is found that the number of cold channels opposite to the air outlet channel is preferably larger, because if the number of cold channels opposite to the air outlet channel is too large, the number of cold channels opposite to the air return channel is likely to be relatively reduced, so that the cooling air flow flows back too slowly, normal circulation of the air flow is affected, and cooling efficiency is reduced. To this end we add further defining features as follows:

Through repeated experiments, the utility model discloses the device can obtain best cooling efficiency when the a/b satisfies above-mentioned ratio scope.
