Description

Technical Field

[0001] The utility model relates to the technical field of ice making, in particular to a pretreatment device for juice freezing and processing. Background Art

[0002] During the production process of fruit juice beverages, the juice raw materials squeezed from fresh fruits are usually stored by freezing. Freezing can effectively inhibit the growth and activities of microorganisms, thereby extending the shelf life of the juice raw materials.

[0003] In the prior art, the juice raw materials are usually directly placed in a cold storage for freezing. However, this storage method usually takes at least one week to completely freeze the juice raw materials into ice, with a long required time and high energy consumption. At the same time, the juice raw materials undergo a long freezing process, resulting in the volatilization and loss of aromatic substances, thus affecting the taste and flavor of the juice raw materials and causing a decline in the quality of the juice raw materials. Content of the Utility Model

[0004] The applicant of the present utility model aims at the above-mentioned disadvantages in the existing production technology and provides a pretreatment device for juice freezing and processing. By setting a scraper assembly and an ice making assembly, the freezing time can be greatly shortened, thereby improving the production efficiency and reducing the energy consumption. At the same time, it can avoid the volatilization and loss of aromatic substances and ensure the juice quality.

One end of the main shaft extends out of the ice making cylinder and is connected to the output end of a driving device. A scraper assembly and an ice making assembly are arranged inside the ice making cylinder, and the ice making assembly is fixed inside the ice making cylinder.

[0007] The ice making assembly includes several ice making plates arranged at intervals. Refrigerant flows inside a single ice making plate. The ice making assembly cools the liquid material inside the ice making cylinder through the refrigerant, so that ice layers are formed on the end faces of the corresponding ice making plates.

The scraper arms are alternately arranged in contact with the ice making plates. The driving device drives the main shaft to rotate, and the main shaft drives the scraper assembly to rotate, so that the scraper arms scrape off the ice layers on the end faces of adjacent ice making plates.

[0012] Several connecting rods are installed between the two cover bodies, and the connecting rods are used to fix the ice-making components.

[0013] Both cover bodies are installed on the main shaft through bearing devices.

[0014] The structure of a single scraper arm is as follows: It includes a mounting shaft, a bushing is installed on the outer circumferential surface of the mounting shaft, several scraping mechanisms are installed on the bushing, the scraping mechanisms are arranged closely along the axial direction of the mounting shaft, and a single scraping mechanism includes two symmetrically inclined scrapers, and the ice layer on the end face of the corresponding ice-making plate is scraped off by the scrapers.

[0017] Several lifting lugs are arranged on the outer wall surface of a single plate body.

[0018] The output end of the driving device is connected to the main shaft through a transmission device.

[0019] The beneficial effects of the present utility model are as follows:

[0020] The structure of the present utility model is compact and reasonable, and the operation is convenient. By setting the scraper assembly and the ice-making assembly, liquid materials such as fruit juice can be precooled to form ice slurry, so that the freezing time can be greatly shortened (it can be completely frozen into ice in 2 - 3 days) during the subsequent freezing process, the production efficiency is improved, and the energy consumption is reduced; at the same time, the whole pre-treatment process is at a low temperature, which can avoid the volatilization and loss of aromatic substances, ensure the taste and flavor of the fruit juice product, and improve the quality of the fruit juice product.
