Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed pressing equipment, in particular to a rapeseed press that is convenient for maintenance. Background Technique

[0002] Rapeseed oil is what we commonly call vegetable oil, also known as rapeseed oil, coriander oil, rape oil, sesame oil, canola oil. It is an edible oil extracted from rapeseed. It is one of the main edible oils in China, mainly produced in the Yangtze River Basin, southwest, northwest and other places, and ranks first in the world in terms of output. After nearly 10 years of efforts in China, the traditional low-quality high-erucic acid rapeseed oil has been transformed into low-erucic acid rapeseed oil with the best nutritional quality among bulk vegetable oils. By 2010, the double-low rate of rapeseed in China reached more than 90%. The human body has a high absorption rate of rapeseed oil, up to 99%. Rapeseed oil has certain effects of softening blood vessels and delaying aging. From the perspective of production process, it can be divided into pressed rapeseed oil and leached rapeseed oil.

[0003] A rapeseed press announced in the Chinese patent with the publication number CN118144350A has the following technical points: including a support plate, the top of the support plate is fixedly installed with a machine body, the inside of the machine body is provided with an operation box, the bottom of the machine body is fixedly installed with an oil storage tank, the outer wall of the machine body is fixedly installed with a slag storage tank, the outer wall of the machine body is fixedly installed with a softening box, and the top of the support plate is fixedly installed with a steam pump.

[0004] The above solution is found to still have at least the following defects in actual operation: the device only softens the cortex of rapeseeds and does not crush the rapeseeds, which easily leads to part of the rapeseed oil remaining inside the fruit shell during pressing, resulting in poor oil output efficiency. Therefore, we propose a rapeseed press that is convenient for maintenance to solve the above problems. Content of the Utility Model
