Problems solved by technology

The shortcoming of this device is that the separation of tomato skin and tomato seed cannot be completed in a set of devices, and the tomato seed and skin are separated by a large amount of water by utilizing the different specific gravity of the skin and seed

Embodiment 1

[0018] The BKY-71 disc shelling machine produced by Henan Daokou Grain Machinery Factory is connected to the shaft of the grinding disc through an inclined auger belt. The two grinding discs and the manual handle are vertically placed on the shaft and installed in the shell. One disc is fixed and the other disc rotates. There are springs between the discs, and the shell is fixed with a steel frame. There is a material inlet on the shell and a material outlet on the bottom. The disc has a diameter of 710 mm and a thickness of 10 mm. The surfaces of the two grinding discs are ribbed with parabolic curves.

[0019] Grind 5 tons of tomato paste with a water content of 10% and use an inclined auger equipped with a 2.2kw power input ф710mm, a power of 17KW, and a disc sheller at the rated speed for grinding; The feeding amount is about 0.8 tons, so that the diameter of the ground material is less than 4mm, and then the manual handle is used to adjust the distance between the grind...

Embodiment 2

[0021] Table 1 and Table 2 are the test data of 13 groups of 5 tons of tomato paste

[0022] Table 1: The separation effect of the first grinding and shelling machine disc spacing change (power matching 17KW)

[0023] Group No

[0024] Group 8

[0025] Table 2: The separation effect of the second grinding and shelling machine disc spacing change (power matching 17KW)

[0026] Group No

[0027] 3

[0028] As shown in Table 1 and Table 2, in the separation process of tomato paste skin and seeds, as long as the water content of tomato paste is kept between 10-12%, the feeding amount of tomato paste is controlled, and the distance between the grinding discs of the disc sheller is adjusted. Grinding for one time, the separation effect of tomato sauce skin and seeds can reach more than 96%.

Abstract

The invention discloses an operation method for separating a crust from seeds of tomato paste by a disk huller. The operation method comprises the following steps: the water content of the fed tomato paste is about 10-20 percent, an inclined packing auger provides 2.2 KW power input with the diameter of 650 mm and the power of 17 KW to grind the disk huller at a rated speed; and a manual handle is used for firstly adjusting a grinding disc distance to be 5 mm and a feeding amount to be about 0.8 ton per hour, and then adjusting the grinding disc distance to be 3 mm to feed the ground materials by 0.4-0.6 ton per hour for once or twice so as to fully separate the crust form the seeds of the tomato paste. The invention overcomes the defect that the prior art can not finish separating the tomato crust form the tomato seeds in a device, adjusts the grinding disc distance of the disk huller by controlling the feeding amount of the tomato paste and grinds the tomato paste twice so that the separation effect of the crust from the seeds of the tomato paste can reach over 96 percent.

Description

technical field [0001] The invention relates to a method for separating the skin and seeds of tomato paste, in particular to achieve the separation of the skin and seeds of tomato paste through a mechanical equipment operation method. Background technique [0002] Tomato waste is a by-product of tomato paste processing, mainly tomato skin and tomato seeds. Among these waste residues, tomato skin is not only rich in calcium, magnesium, phosphorus, potassium, sodium and other mineral elements, but also contains lycopene; tomato seeds are ideal raw materials for nutrients such as vegetable oils, unsaturated fatty acids, and high-lysine proteins. At present, the waste residue of tomato paste seeds in my country has reached more than 100,000 tons. Therefore, in order to extract nutrients from these waste residues, people have developed a variety of cleaning and separation devices for tomato waste residue, skin and seeds. Chinese patent (Patent No.: 00126542.3) discloses a separ...
