Oil Expeller Matched Machines Edible oil is our daily deal, but edible oil in the processing and storage process has to pay attention, otherwise it is easy to harm our health.
Oil rancidity
Long-term storage of oil under certain conditions will occur a series of chemical changes, the sensory properties of oil adverse effects, this change is the oil rancidity, oil rupture will have Hala taste, rich in fat food there are such problems. Oxidation of oil produced by the decomposition of free fatty acids, resulting in ketones, aldehydes and peroxides, which not only changes in oil properties, more importantly, the process of ketones, aldehydes and peroxidation are toxic, unfavorable.
Cause of rancidity
There are two reasons why the fat is rancid, there are two main reasons for the loss of raw materials in the grease and the enzymes produced by the microorganisms. These substances play the role of biological enzymatic hydrolysis. The second reason is of course the oil itself in the air,Oil Expeller Matched Machines sunlight and water. Factors under the action of hydrolysis and unsaturated fatty acid self-oxidation.
Grease quality control is stress
In order to ensure the safety of food consumption, China's limited amount of water in the grease (not more than 0.2%), and requires the addition of antioxidants in edible oil, of course, first of all require high purity of edible oil, storage conditions must meet the requirements, such as Placed in an opaque container or green, brown glass bottle, and sealed, protected from light in the shade. Many people are only concerned about the process of oil extraction, ignoring the details of oil preservation, resulting in oil storage problems in the storage phase.
Peanut is a common oil crop, peanut oil is also our common cooking oil, but this kind of oil seeds are easily contaminated by mold, Aspergillus flavus contaminated peanuts will produce toxins,Oil Expeller Matched Machines these substances will be with the process of oil into the edible oil , Such substances are clear and highly carcinogenic substances. Standard oil production is to be tested on the raw materials, while the use of alkali refining and adsorption can effectively remove these toxins, while the production of edible oil should also be tested, the state of edible oil in the retention of some substances There are provisions, more than the provisions of the amount is substandard products, prohibited sales.
A: When the production is reduced, in addition to the cake or the oil is not normal, the squeeze should be squeezed out, check the squeeze screw, squeeze, out of the cake mouth wear, wear parts to be replaced.
Two: 50 hours of work should be checked when the lubrication,Oil Expeller Matched Machines the gear box which is not allowed to lack of oil, oil extraction equipment, squeeze the screw shaft to adjust the screw bearing from the adjustment screw hole caught butter once, is strictly prohibited dry grinding.
Three: the lubrication parts should be to prevent dust and other debris immersion, the annual need to check the oil crusher oil tanker quality, such as found deterioration, should replace all the oil.
Four: the end of the production season after the long-term storage,Oil Expeller Matched Machines should be a maintenance, and squeeze the screw, squeeze the material, the cake back and forth after the re-assembly of oil, all the oil press on the dry place.
