A screw oil press with a circulating cooling system

Abstract

The invention discloses a spiral oil press with a circular cooling system. The spiral oil press comprises a press unit used for containing a material to be pressed and finishing press operation, a base used for supporting the press unit and an air cooling circulation unit, the base is internally provided with an electric heating temperature control unit and a water cooling circular cooling unit which are matched with the press unit, the air cooling circulation unit is arranged above the press unit and communicates with the interior of a press cage of the press unit, at least one wall breakingcutting mechanism is detachably arranged on a feeding press screw segment, a ventilation hole is formed in the matching position of a shell and an air inlet pipe, and a ventilation assembly matched with the end of the air inlet pipe is arranged on the ventilation hole. The spiral oil press with the circular cooling system is provided, equipment cost controllability and stability of a product can be ensured, meanwhile, the temperature of the press unit is controlled, the work state is stable, product oil outlet is improved, and the nutrition component is higher.

Description

Technical field [0001] The invention relates to an oil press used in industrial production. More specifically, the present invention relates to a screw oil press with a circulating cooling system used in the case of vegetable oil pressing. Background technique [0002] Oil press refers to the oil-squeezing equipment that squeezes grease from vegetable oils with the help of external mechanical force. At present, the most widely used oil press on the market is the screw oil press. Its structure is mainly composed of a base, an electric control device, a cage assembly, a feeding mechanism, a reduction mechanism, an adjustment mechanism and a screw shaft. It has the advantages of large continuous processing capacity, short dynamic pressing time, high oil yield and low labor intensity. [0003] However, when the traditional screw oil press is working, the vegetable oil is continuously squeezed in the press chamber for a long time, which makes the press chamber heat up too high. When t...

Problems solved by technology

[0003] However, when the traditional screw press is working, the temperature of the press chamber is too high due to the continuous pressing of vegetable oil in the press chamber for a long time. Insufficient moisture causes coking of the raw material, causing the protein denaturation of the vegetable oil to exceed the limit, destroying various vitamins, fatty acids, minerals, trace elements and nutrients in the vegetable oil, and affecting the quality of the oil, such as blackening of the oil , lose the original fragrance of the oil, and make the dry cake black and coke, which affects the use value of the dry cake; at the same time, the frictional heat is too high, which reduces the friction resistance between the embryo particles, thereby reducing the pressure of the pressing chamber , to reduce the oil yield of the material embryo

[0004] For the existing patented technology, such as the patent document "Screw Oil Press with Circulating Water Cooling System", a solution is proposed, which can realize partial control of the temperature in the press chamber, but the rotating shaft part is One-piece design, and the part with more serious wear of the shaft is usually only localized, such as the pressing screw section, if it is replaced as a whole based on it, it will affect the cost in the production process. The screw section is the standard, which will affect the oil output rate of the product, and water is passed through the shaft to cool down. If the water inlet and outlet pipes do not move, but only the shaft moves, the inlet and outlet ports must correspond to the cavity in the shaft. , and the sealing operation must be done well. If the inlet and outlet pipes and the rotating shaft rotate at the same time, it will affect the working state of the water pipes and the working state of the entire production process. , it is easy to cause the oil to be thrown from one oil outlet to another oil outlet under the action of rotation during the rotation of the shaft, which affects the pressing progress and oil output effect, and affects the pressing effect of the equipment
