Embodiment 1

[0013] A kind of production method of corn oil, comprises the following steps:

[0014] 1) take corn germ and dry until the moisture content is 2%, and the germ dander content is 8%;

[0015] 2) using a roller crusher to grind the dried corn germ;

[0016] 3) wet the ground corn germ with water until the water content is 5%, and make oil cake;

[0017] 4) put the oil cake into an oil press, and press the oil at 100°C to make corn crude oil;

[0018] 5) Use a decanter centrifuge to filter corn oil at a speed of 3000 rpm to make corn oil.

Embodiment 2

[0020] A kind of production method of corn oil, comprises the following steps:

[0021] 1) take corn germ and dry until the water content is 3%, and the germ dander content is 10%;

[0022] 2) using a roller crusher to grind the dried corn germ;

[0023] 3) wet the ground corn germ with water until the water content is 5.5%, and make oil cake;

[0024] 4) put the oil cake into an oil press, and press the oil at 105°C to make crude corn oil;

[0025] 5) Use a decanter centrifuge to filter corn oil at a speed of 4000 rpm to make corn oil.

Embodiment 3

[0027] A kind of production method of corn oil, comprises the following steps:

[0028] 1) take corn germ and dry until the water content is 4%, and the germ dander content is 12%;

Abstract

The invention belongs to the technical field of edible vegetable oil products, in particular to a method for producing corn oil. The method is mainly used for solving the technical problems that the whole productive technology can not realize full-automation, labor intensity of workers is high, quality of refined oil products is unstable, and the maintenance of a plate-and-frame filter press is troublesome when the plate-and-frame filter press is used for filtering the corn oil currently. The technical scheme of the method is as follows: (1) drying corn germs; (2) crushing the dried corn germs by using a roll crushing machine; (3) moistening the crushed corn germs with water until moisture content reaches 5-6%, and then preparing into oil cakes; (4) putting the oil cakes into an oil press, and pressing oil at a temperature of 100-110 DEG C to prepare into corn crude oil; and (5) filtering the corn crude oil by using a horizontal decanter centrifuge at revolving speed of 3000-5000rpm to obtain the corn oil. The method disclosed by the invention has the advantages of simple technological conditions, low labor intensity of the workers, stable quality of the refined oil products and simple maintenance and the like, and being capable of realizing full-automatic production.

Description

technical field [0001] The invention belongs to the technical field of edible vegetable oil products, and in particular relates to a production method of corn oil. Background technique [0002] At present, the mud removal process in the corn oil production process mostly uses a plate and frame filter press to filter and remove mud. The filtered corn oil is golden yellow and transparent, and must not be turbid. The pressure during filtration should not be too high. If the pressure is too high, the product oil will be turbid, which will reduce the quality of the oil, and the filter mud will often block the filter. In order to ensure the normal operation of the plate and frame filter press, professional staff must monitor the filter press in real time. When the pressure of the filter press changes, if the pressure is found to be too high, the entire desilting process will be stopped, and the plate and frame filter press will be disassembled by a special person to clean the oil ...
