Process Characteristics

  The unique aroma of natural flavor peanut oil has a lot to do with its production process, which is applied to common soybean, peanut and rapeseed. This process roasts the material to produce aroma to increase the flavor of the oil; and then uses low-temperature special filtration technology to remove the colloid in the pressed crude oil, so as to achieve the retention of flavor while improving the standard of oil.

  Let’s take the fragrant peanut oil as an example:

  In order to maintain its natural color, aroma and taste, the natural flavor peanut oil is generally not subjected to hydration, alkali refining, decolorization and deodorization treatment.

  The raw materials must be fresh, high-quality peanuts with full grains. Immature kernels, damaged kernels, mildewed kernels, and aged kernels must not be used for production.

1.Cleaning process:

In order to obtain high quality oil, the raw material from the warehouse must be cleaned to remove second seeds, bad seeds and other impurities in the raw material. The separated parts, such as second seeds and bad seeds, can be mixed with the separated skin parts to be used as raw materials for boilers or pressed separately into feed oil or industrial oil.

This process uses equipment such as permanent magnet cylinders, specific gravity stone removers, and vibrating cleaning screens to remove impurities such as sediment, stones, tiles, and metals, so as to avoid strong friction on the equipment, which will cause greater damage to the equipment, thereby prolonging the life of the equipment. service life. Clean up impurities such as stems and leaves, husks, wormwood, hemp rope, etc., to avoid darkening of crude oil, increase of sediment, and increase of refining consumption. Too many impurities in the cake will reduce its use value. If the impurities occupy a certain volume, it will also increase the burden on the equipment. At the same time, the wormwood and hemp rope long fiber impurities in the oil are easy to wrap around the rotating shaft of the equipment, affecting the process. As a result, power consumption will be increased, and even the import and export of equipment will be blocked, resulting in production accidents and equipment failures.

2.Grading: Use a grading sieve to separate immature kernels, mildewed kernels, broken kernels and other imperfect kernels in peanuts. This part can be used to produce secondary oil and sold separately.

3.Drying/cooling:After the peanuts are dried, the moisture should be controlled at 5%~6%. Then quickly use cold air to lower the temperature of the oil particles below 40°C.

4.Crushing/peeling: Peel off the red skin of peanuts, and after crushing, use a wind separator or a suction flat sieve to suck out the red skin. The separated red skin of peanuts can be used as raw materials for medicine and chemicals.

5.Hot roasting: send 25%~30% of the total amount of peanut petals to the frying pan, and directly heat to 180°C~200°C. Roasting temperature is the key factor for the fragrance of natural flavor peanut oil. If the temperature is too low, the fragrance will be weak; if the temperature is too high, the oil will easily gelatinize.

  If a vertical steaming wok is used for steaming and frying: use a five-layer vertical steaming wok to steam and fry the green body. The 1st~2nd layer should be filled with material to steam; the 3rd~5th layer should be filled with shallow material to remove moisture; the discharge temperature is 108℃～112℃, and the water content is 5%～7%. To ensure that the peanut oil has a strong fragrance, the indirect steam pressure of the steam frying boiler should not be less than 0.6mpa.

6.Cool down and crushing:In order to prevent gelatinization and spontaneous combustion of the oil, the heat should be dissipated and cooled quickly after frying, and crushedinto granules after cooling.

7.Oil pressing:The pressing efficiency of the oil press and the stability of the equipment are the key to the oil pressing process. It is pressed by powerfulscrew oil press, which has the characteristics of high temperature pressing, and the obtained oil has a strong fragrance.
