Problems solved by technology

[0004] It is difficult to control the proper temperature and time by using the method of stir-frying. If the temperature is too high, the vegetable oil will be carbonized or partially carbonized, resulting in low oil yield, oil deterioration, and black or dark color. If the temperature is too low , it will result in high moisture content and lack of fragrance.
[0005] When heating the vegetable oil in the above-mentioned methods, one furnace, one pot and other containers are used for heating at one time, and after the heating is completed, all of them are put into the press for pressing, so the pressing of the press is interrupted.
[0006] At the same time, the above-mentioned method also needs to preheat the press, otherwise the oil yield will be extremely low at the beginning of pressing, and the quality of the oil will be very poor

Embodiment 1

[0025] Vegetable oil is a compound composed of unsaturated fatty acid and glycerol. It is widely distributed in nature and is the oil obtained from the fruit, seed and germ of plants.

[0026] Common vegetable oils include peanut kernels, rapeseed kernels, sunflower kernels, soybeans, camellia kernels, almonds, walnut kernels, cashew kernels, etc.

[0027] In this embodiment, peanut kernels are taken as an example to illustrate the technical solution of the present invention. The case of peanut kernels can be referred to for the pressing process of other vegetable oils.

[0028] Step 1: Preheat the extruder by dry pressing peanut bran, or electrify and heat the extruder with electric heating function, so that the preheating of the extruder reaches the normal working temperature of 170°C or above.

[0029] Step 2: Use hot air to roast peanut kernels. The temperature range of the hot air is greater than or equal to 110°C and less than 190°C. The preferred temperature is about 17...

Embodiment 2

[0045] Example 1 is optimized as follows.

[0046] In order to make the roasting more even, before roasting, open the sides of the peanut kernels and remove the red coat. This treatment results in a more even roast and a clearer peanut oil after removing the red coat.

[0047]The aromatic substances of peanut oil are produced from the chemical reaction at a higher temperature of peanut kernels. The longer the chemical reaction time, the more aromatic substances are obtained and the stronger the fragrance. For this reason, after the peanut kernels obtained after step 2 in Example 1 are separated from the roasting device, they are delayed for 1-8 minutes and then sent to the press for pressing. This way can make the obtained vegetable oil more fragrant.

Embodiment 3

[0049] In step one of Example 1, if the way of dry pressing peanut bran is used to preheat the extruder, it will take a lot of labor and time; if the extruder with electric heating function is used for electric heating, no additional labor is required, but it still needs It takes 20 minutes or even longer, and both of these two preheating methods generate a certain amount of energy consumption.

[0050] To this end, hot air with a temperature higher than 190°C can be used to roast peanut kernels, so that the surface of the roasted peanut kernels is close to or reaches the critical state of carbonization, and then the peanut kernels whose appearance is close to or reach the critical state of carbonization can be sent to the press without heat engine. machine, press for 5-15 minutes until the temperature of the press machine reaches the normal operating temperature, and then enter step three. The preheating method is actually direct pressing, which by the way plays the role of p...

Abstract

The invention specifically relates to a method for preheating a presser to press out vegetable oil with strong aroma, which belongs to the technical field of pressing of a vegetable oil material. According to the method, the presser is preheated, hot air with a temperature of more than or equal to 110 DEG C and less than 190 DEG C is used to bake a vegetable oil material, and then normal pressing is carried out. To better improve product quality, the invention also provides an approach of baking the vegetable oil material by using hot air with a temperature of more than 190 DEG C at first so as to allow the surface of the vegetable oil material to approach or reach a critical charring state and then delivering the vegetable oil material to the press which is not preheated for pressing, and through such operation, the presser is preheated in passing; then the temperature of the hot air for baking the vegetable oil material is reduced, and a normal pressing procedure is carried out; and the presser can continuously works without interruption. Moreover, as the hot air is used for baking the vegetable oil material during pressing, hot air temperature and baking time can be accurately controlled, so the vegetable oil material can be completely prevented from charring and deterioration under the condition of high temperature; and thus, the quality of the vegetable oil is improved.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil pressing, and specifically relates to a method for pressing a strong-flavored vegetable oil with a preheating press. Background technique [0002] Heating the vegetable oil and then pressing it can make the obtained vegetable oil have a strong fragrance. The traditional processing method is heating by steaming or stir-frying, wherein the stir-frying method includes charcoal fire heating, electric heating wire heating or microwave heating. [0003] The cooking method can avoid overheating of the vegetable oil, but due to the low temperature and high water content, the quality of the obtained vegetable oil is not high, and the fragrance is also lacking. [0004] It is difficult to control the proper temperature and time by using the method of stir-frying. If the temperature is too high, the vegetable oil will be carbonized or partially carbonized, resulting in low oil yield, oil deterioration...
