Description

[0001] This is a divisional application of PCT Application No. PCT/CN2019/083110 fded on 17 April 2019, the entire contents of which are hereby incorporated by reference.

[0002] The present invention belongs to the field of vacuum tumbler equipment technologies, and in particular, to an electromagnetic vibration vacuum tumbler with four degrees of freedom.

DESCRIPTION OF RELATED ART [0003] A vacuum refrigerating and tumbler makes, by using a physical impact principle, materials turn up and down in a tumbling barrel, and strike and rub with each other, to produce the massaging and pickling effect evenly distributed in a large area. The even distribution of pickling liquid in the materials is more conducive to maximize the precipitation of salt soluble protein at the fastest speed, so as to increase the water holding capacity of the products, well improve the elasticity, slicing and taste of the product, and greatly improve the product yield. However, the existing vacuum tumbler has only one movement degrees of freedom with one rotation of a tumbling barrel. Consequently, the meat products, the spices, and the pickling liquid may not be mixed thoroughly and evenly, and it is hard to pickle food. An effect of absorption of the materials such as meat for the spices is poor, the tumbling is time-consuming, and it is hard to clean the tumbling barrel. The meat may stick on the cylinder surface in the tumbling process, and residues sticking on the cylinder after the tumbling are hard to be removed, so that it is inconvenient to clean the tumbler. If a tumbling time is relatively long, the meat may produce heat through friction in the tumbler, which makes the meat heated unevenly in the tumbling barrel and affects the taste.

[0004] To resolve the problem of the small quantity of movement degrees of freedom of the tumbling barrel, some solutions have been put forward in the existing patent documents. For example, the Chinese utility model patent NO. 201320845561.2 discloses a magnetic vibration vacuum tumbler. An external surface of an inner barrel of the tumbling barrel is provided with

2019101660 20 Dec 2019 evenly distributed vibration core housings, and the vibration core housing is provided with an electromagnetic vibration core. A middle-upper part of a bracket is provided with an electromagnetic plate, and a hollow area between the inner barrel and the housing is provided with heating oil. The electromagnetic plate heats the heating oil and magnetic intensity of the electromagnetic plate is adjusted to change the intensity of the electromagnetic field, so as to achieve an objective of heating and vibrating the electromagnetic vibration core. Although this technical solution can implement vibration of the tumbling barrel, the vibration direction is single, and the mixing effect of meat products in the tumbling barrel is limited.
