Embodiment 1

[0034] A kind of high-quality olive kernel oil preparation method, comprises the following steps:

[0035] 1) Baking: Set the heat pump drying temperature to 60°C, the drying time to 20 hours, and the drying moisture to 5%. The purpose is to increase the brittleness and storability of olive stones for later crushing and storage.

[0036] 2) Crushing: Use a high-speed pulverizer to crush the olive core into 20-mesh particles.

[0037] 3) Vibrating sieving: Use a 45-mesh vibrating sieve to sieve and remove some fine-grained olive kernels. The separation of olive kernels and olive cores can reach 99%.

[0038] 4) The olive nuclei are first assisted by ultrasonic wave and then heated by microwave through the auxiliary processing equipment of ultrasonic and microwave heating: the frequency of ultrasonic wave is 120w, and the time is 4min. The purpose is to use the ultrasonic "empty drum effect" to accelerate the separation of grease; after stopping the ultrasonic wave, select micr...

Embodiment 2

[0052] A kind of high-quality olive kernel oil preparation method, comprises the following steps:

[0053] 1) Baking: Set the heat pump drying temperature to 55°C, the drying time to 22 hours, and the drying moisture to 6%. The purpose is to increase the brittleness and storage of olive stones for later crushing and storage.

[0054] 2) Crushing: Use a high-speed pulverizer to crush the olive core into 30-mesh particles.

[0055] 3) Vibrating sieving: Use a 40-mesh vibrating sieve to sieve and remove some fine-grained olive kernels. The separation of olive kernels and olive cores can reach 99%.

[0056] 4) The olive nuclei are ultrasonically assisted by the combined auxiliary treatment equipment of ultrasonic and microwave heating, and then heated by microwave: the frequency of the ultrasonic wave is 130w, and the time is 4.5min. The material turning device in the combined auxiliary treatment equipment of ultrasonic and microwave heating is forward , the purpose is to use the...

Embodiment 3

[0070] A kind of high-quality olive kernel oil preparation method, comprises the following steps:

[0071] 1) Baking: Set the heat pump drying temperature to 65°C, the drying time to 30 hours, and the drying moisture to 7%. The purpose is to increase the brittleness and storability of the olive stones for later crushing and storage.

[0072] 2) Crushing: Use a high-speed grinder to crush the olive core into 40-mesh particles.

[0073] 3) Vibrating sieving: 50-mesh vibrating sieve is used to sieve, and some fine-grained olive kernels are removed, and the separation of olive kernels and olive cores can reach 99%.

[0074]4) The olive nuclei are first assisted by ultrasonic wave and then heated by microwave through the auxiliary processing equipment combined with ultrasonic and microwave heating: the frequency of ultrasonic wave is 160w, and the time is 6min. Its purpose is to use the ultrasonic "hollow drum effect" to accelerate the separation of grease; after stopping the ultr...

Abstract

The invention relates to a preparation method of high-quality olive kernel oil. The preparation method comprises the following steps: setting the drying temperature of a heat pump to be 55-65 DEG C, setting the drying time of the heat pump to be 20-30 hours, and setting drying moisture to be 5-7%; crushing olive kernels into 20-40-mesh particles by using a high-speed crusher; carrying out screening by using a 40-50-mesh vibrating screen, and taking lower-portion fine-particle olive kernels; performing ultrasonic-assisted treatment on the fine-particle olive kernels through ultrasonic and microwave heating combined auxiliary equipment, and performing microwave heating after ultrasonic treatment is stopped; discharging the olive kernels into a barrel of a presser, and carrying out pulse direct pressure pressing with pressing pressure set to be 100 t to 150 t and pressing time set to be 0.5 h to 1 h; pumping squeezed olive kernel oil into a storage tank, then pumping the oil into a filtering device through a high-pressure pump, and carrying out filtering; and taking a sample, and determining the oxidation resistance and the olive polyphenol content of the olive kernel oil.

Description

technical field [0001] The invention relates to a method for preparing high-quality olive kernel oil. Background technique [0002] As one of the oldest edible oils, olive oil has various health benefits. At present, what is sold on the market is olive oil pressed from European olives, while olive kernel oil is oil obtained by pressing Chinese olive kernels. With the rapid development of residents' consumption ability, people's demand for quality and quantity of olive oil is also increasing. At present, the old olive oil production equipment often uses physical methods to directly squeeze the olive kernels. This method is often difficult to completely squeeze out the oil, and the material utilization rate is low, resulting in a large waste. And use centrifugal structure or vibrating screen structure to separate olive pomace and oil. These production equipments have the defect that it is difficult to completely remove the pomace and cause the oil to rot, which has been dif...
