Abstract
Description
Technical Field
[0001] The invention relates to the technical field of food processing, in particular to a green plum juice extraction processing technology. Background Art
[0002] Green plums are rich in nutrients and are known for their sour taste. The flesh contains a variety of vitamins, amino acids, citric acid, malic acid, tartaric acid, and mineral elements such as potassium, calcium, and iron, and is a strongly alkaline physiological fruit. When making most green plum products, the green plums need to be washed and pulped to make green plum juice. The existing green plum juice processing technology has the problems of incomplete washing and low pulping juice extraction rate. Summary of the invention
[0003] In view of the shortcomings of the prior art, the main purpose of the present invention is to provide a green plum juice extraction processing technology with thorough cleaning and high juice yield.
[0004] To achieve the above object, the present invention provides the following technical solution: a green plum juice extraction process, comprising the following process steps: (1) Drum impurity removal: Green plums are removed by rotating screens and spraying pure water; (2) Bubble cleaning: inject high-pressure gas into the water to make the green plum enter surfing-style cleaning to remove surface stains; (3) Brush cleaning: The green plum turns on the 360° rotating brush to clean without dead corners; (4) Pre-cooking: pre-cook the green plums at low temperature to soften them, and then quickly cool the pre-cooked green plums; (5) Peeling and core removal: After the green plums are cleaned, the core and skin are removed by a core removal machine to obtain green plum puree; (6) Pulping: Pour the green plum pulp obtained in step (5) into a pulping machine for pulping to separate the pulp from the residue and obtain green plum juice.
[0005] Preferably, the mesh size of the rotary screen in step (1) is about 10 mm.
[0006] Preferably, the speed of the beater in step (6) is 1200-1500 r / min.
[0007] Preferably, in step (4), the green plums are cooled by a spray cooling and cleaning method.
[0008] The present invention has the following advantages over the prior art. It can thoroughly remove impurities and clean green plums through three cleaning processes of drum cleaning, bubbling cleaning and brush cleaning. The green plum raw materials are required to be large, thick, without scars, rotten or deteriorated, with hard cores and a maturity of 50% to 60%. The selected green plums enter the rotating screen from the feed inlet and are continuously turned over. When turning over, pure water is sprayed on the top of the screen to clean the impurities and leaves in the green plums, thereby achieving a preliminary screening and cleaning. During bubbling cleaning, the green plums enter the secondary cleaning, and high-pressure gas is flushed into the water to make the green plums enter the surfing cleaning to remove surface stains. During brush cleaning, the green plums enter the tertiary cleaning, and the green plums are turned over on the 360° rotating brush, so that there is no dead angle cleaning.
[0009] After peeling and pitting, the cleaned green plums are sent to the pitting machine to remove the hard core and skin inside, so as to obtain about 85% of green plum puree. After the puree enters the high-speed pulping machine, a more delicate puree comes out, so as to achieve pulp-residue separation and reach a juice yield of 80%~90%. The green plums in this solution are thoroughly cleaned and have a high juice yield, and the product quality and production efficiency are better than the existing processing technology. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 The present invention is a flow chart of a green plum juice extraction process. Implementation
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] like Figure 1 As shown, a green plum juice extraction process includes the following process steps: (1) Drum impurity removal: Green plums are removed by rotating screens and spraying pure water; (2) Bubble cleaning: inject high-pressure gas into the water to make the green plum enter surfing-style cleaning to remove surface stains; (3) Brush cleaning: The green plum turns on the 360° rotating brush to clean without dead corners; (4) Pre-cooking: pre-cook the green plums at low temperature to soften them, and then quickly cool the pre-cooked green plums; (5) Peeling and core removal: After the green plums are cleaned, the core and skin are removed by a core removal machine to obtain green plum puree; (6) Pulping: Pour the green plum pulp obtained in step (5) into a pulping machine for pulping to separate the pulp from the residue and obtain green plum juice.
[0013] The green plum juice extraction processing technology of the present scheme can thoroughly remove impurities and clean the green plums through three cleaning processes of drum cleaning, bubbling cleaning and brush cleaning. The green plum raw materials are required to be large, thick, without scars, rotten or deterioration, with hard cores and a maturity of 50% to 60%. The selected green plums enter the rotating screen from the feed inlet and are continuously turned over. When turning over, pure water is sprayed on the top of the screen to clean the impurities and leaves in the green plums, thereby achieving a preliminary screening and cleaning. During bubbling cleaning, the green plums enter the secondary cleaning, and high-pressure gas is flushed into the water to make the green plums enter the surfing cleaning to remove surface stains. During brush cleaning, the green plums enter the tertiary cleaning, and the green plums are turned over on the 360° rotating brush, and there is no dead angle cleaning.
[0014] After peeling and pitting, the cleaned green plums are sent to the pitting machine to remove the hard core and skin inside, so as to obtain about 85% of green plum puree. After the puree enters the high-speed pulping machine, a more delicate puree comes out, so as to achieve pulp-residue separation and reach a juice yield of 80%~90%. The green plums in this solution are thoroughly cleaned and have a high juice yield, and the product quality and production efficiency are better than the existing processing technology.
[0015] Preferably, the mesh size of the rotary screen in step (1) is about 10 mm. A mesh size of about 10 mm can effectively remove impurities and leaves while ensuring that the green plums will not fall off.
[0016] Preferably, the speed of the pulping machine in step (6) is 1200-1500 r / min. A high speed can achieve better crushing effect of the green plums and obtain finer raw pulp.
[0017] Preferably, in step (4), the green plums are cooled by spray cooling and cleaning. This method can cool the green plums evenly and quickly, and also achieves a further cleaning effect.
[0018] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
