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 grinding disc shaft through the inclined screw conveyor belt. The two grinding discs and the manual handle are placed on the shaft vertically and installed in the shell. One disc is fixed and the other rotates. A spring is arranged between the plates, and the shell is fixed by a steel frame. There is an inlet on the shell and an outlet on the bottom. The diameter of the grinding disc is 710 mm and the thickness is 10 mm. The surface of the two grinding discs is ribbed with parabolic curve.

[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 φ710mm, a power of 17KW, and a disc sheller at rated speed for grinding; first use a manual handle to adjust the distance between the grinding discs to 5mm, per hour The feeding amount is about 0.8 tons, so that the diameter of the ground material is below 4mm,...

Embodiment 2

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

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

[0026] Group No

[0027] 3

[0028] As shown in Table 1 and Table 2, in the process of separating the ketchup skin and seeds, as long as the water content of the ketchup is kept between 10-12%, the ketchup feeding amount is controlled, and the distance between the plates of the disc peeling machine is adjusted. After grinding, the separation effect of ketchup 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 isused 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 materialsby 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 tomato paste skin and seeds, in particular to a method of mechanical equipment operation to achieve the separation of tomato paste skin and seeds. Background technique [0002] Tomato waste is a by-product of tomato paste processing, mainly including tomato skin and tomato seeds. Among these waste residues, tomato skins are not only rich in mineral elements such as calcium, magnesium, phosphorus, potassium, and sodium, but also 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 ketchup skin and seeds in my country has reached more than 100,000 tons. Therefore, in order to extract nutrients from these waste residues, a variety of tomato waste residue skin and seed cleaning and separation devices have been developed. A Chinese patent (Patent No.: 00126542.3) discloses a separation device for t...
