A stone mill with a pre-crushing function

Abstract

The present invention relates to a stone mill with a pre-crushing function, comprising a power mechanism, characterized in that a power motor is installed below a connecting seat via an external hexagonal bolt, a cylinder mechanism with a lifting function is installed below the power motor, a transmission shaft in the power mechanism is connected to an output shaft sleeve of the power motor; the transmission shaft is connected to a rotating member in a top-level stone mill mechanism, and when the power motor rotates, the top-level stone mill mechanism rotates accordingly, and relative movement occurs between the top-level stone mill and the lower-level stone mill, so as to achieve the effect of crushing and grinding soybeans; a pre-grinding head and a pre-grinding sleeve are installed inside the rotating member The pre-grinding head and pre-grinding sleeve pre-crush the beans. Pre-crushing has three main benefits: First, pre-crushing reduces the size of the soybeans, eliminates the coarse grinding marks on the millstone, lengthens the fine grinding marks, and reduces wear on the millstone, thereby reducing repair and maintenance costs. Second, pre-crushing shortens the time it takes to crush and grind the beans within the millstone, thereby improving mill efficiency. Third, pre-crushing makes it easier to grind the beans thoroughly, resulting in a smoother, milk-like soy milk. This saves raw materials while retaining the original nutrients, fully utilizing the advantages of the millstone. In addition to raising and lowering the top millstone, the cylinder mechanism also increases the pressure between the top and lower millstones to achieve a finer grinding effect.

Description

Technical Field

[0001] The invention belongs to food processing machinery, in particular to a stone mill with a pre-crushing function for making foods such as soya milk, bean curd, and bean curd. Background Art

[0002] Soy milk, tofu pudding and tofu are the most popular foods. Soy milk can also be processed into a variety of bean products. It can also be used to grind a variety of grains. There are two main types of processing equipment commonly used in the market: one is a two-layer stone mill driven by a motor, and the other is an electric grinding wheel mill. The main disadvantages are:

[0003] 1. Existing double-layer stone mills mostly use eccentric feeding and simply rely on the force between the two stone mills to process beans. The processed soy milk is rough, contains a lot of bean dregs, wastes raw materials, has poor quality, low efficiency, and low output.

[0004] 2. After each operation, the various cavities and material flow channels of the stone mill must be cleaned. The existing stone mills on the market rely on manual lifting of the top stone mill or using a jack to lift the top stone mill for cleaning, which is time-consuming and labor-intensive, affecting production efficiency.

[0005] 3. The existing double-layer stone mill is rigidly connected and driven by the motor and various mechanical parts. It will generate huge impact force at the moment of startup. Long-term use will easily damage the stone mill and transmission parts, resulting in high maintenance costs and affecting efficiency.

[0006] 4. Electric grinding wheel grinding requires repeated grinding each time, which causes loud noise and vibration, and there is sand in the bean dregs, which makes them inedible. Summary of the Invention

In addition to realizing the lifting function of the top stone mill, the cylinder mechanism also has the function of adjusting the force between the top stone mill and the lower stone mill, slowing down the damage of the stone mill and other technical problems, a stone mill with a pre-crushing function.

[0008] The present invention solves the technical problem, and the technical solution adopted is:

[0009] The cam is fixed on the top of the gear train, and the cam is fixed on the gear train, and the cam is fixed on the gear train, and the cam is fixed on the gear train.
