Goji Berry Extraction Machine with Goji Berry Residue Collection Device

Abstract

This utility model discloses a goji berry residue collection device for a goji berry pressing machine, including a goji berry pressing machine. The residue from the machine's discharge end is conveyed to a vibrating screen via an elevator. The vibrating screen is equipped with a primary and a secondary screen. The residue is screened out through the primary screen, and the seeds are screened out through the secondary screen. This goji berry residue collection device disperses the pressed and agglomerated residue through the vibrating screen, separates the seeds to be recovered, and other impurities such as peels and stems enter a drying device. After drying, the peels and seeds shrink and dry due to water loss, weakening their binding force. After being conveyed by air, they collide in the separation chamber, separating the peels and seeds. The seeds are then recovered by air separation and returned to the vibrating screen for further processing. This method results in low impurity content and high recovery rate in the recovered seeds.

Description

Technical Field

[0001] This utility model relates to the technical field of goji berry pressing equipment, specifically a goji berry residue collection device for an integrated goji berry pressing machine. Background Technology

[0002] Industrial processing of raw goji berries is a relatively complex process, including raw material procurement and acceptance, cleaning, crushing, juicing, filtering, sterilization, blending, and bottling. The extracted juice contains impurities such as pulp and peel, which need to be filtered by filtration equipment. Commonly used filtration equipment includes plate and frame filter presses, diatomaceous earth filters, and precision filters. First, coarse filtration is performed using a plate and frame filter press to remove larger particles of impurities, and then fine filtration is performed using a diatomaceous earth filter or a precision filter.

[0003] After raw pressing, goji berries are mainly divided into juice and pulp. The juice is sent for purification and processing to become the main product, while the pulp is generally used to make feed or directly fed to poultry. The pulp includes seeds, peel, stems, and a small amount of branches and leaves. The peel, stems, and small amount of branches and leaves have low utilization value, but the seeds have certain recycling value. Goji berry seeds contain a variety of nutrients, such as protein, fat, vitamins, minerals, and some bioactive substances. Through professional extraction technology, these nutrients can be extracted from goji berry seeds for use in health products, cosmetics, and other fields. For example, goji berry seed oil is extracted from goji berry seeds. It is rich in unsaturated fatty acids, has high nutritional value and certain health benefits, and can be used to make nutritional supplements or added to skin care products, with moisturizing and antioxidant effects. Therefore, this application proposes a technological improvement to recycle goji berry seeds. Utility Model Content

[0015] Please see Figure 1In this embodiment of the utility model, the wolfberry residue collection device of the wolfberry fresh-pressing machine includes a wolfberry fresh-pressing machine 1. The residue outlet of the wolfberry fresh-pressing machine 1 is fed to a vibrating screen 3 by an elevator 2. The vibrating screen 3 is equipped with a primary screen 4 and a secondary screen 5. The fruit residue is screened out through the primary screen 4, and the fruit seeds are screened out through the secondary screen 5. In this application, a vibrating screen 3 is provided at the residue outlet of the wolfberry fresh-pressing machine 1. The residue is fed to the vibrating screen 3 by an elevator 2. The vibrating screen 3 has two... The first function is to disperse the fruit pomace under the excitation force of the vibrating screen 3, thus breaking up any clumps of pomace after pressing. The second function is to filter out the fruit pomace, which includes seeds, peels, and leaves through the screen size of the primary screen 4, while the seeds fall through. The bottom of the secondary screen 5 is equipped with a conveyor belt 7, through which the seeds are output. The seeds can be directly sent to the pressing equipment for processing into residue oil, or temporarily stored in a storage tank for sale.

[0016] In a preferred embodiment, the fruit residue screened out by the primary sieve 4 is sent to the drying equipment 6. The fruit residue output from the drying equipment 6 enters the transfer chamber 8 and is connected to the Venturi tube 10 through the discharge valve 9. The air inlet end of the Venturi tube 10 is connected to the blower 11, and the output end of the Venturi tube 10 is connected to the separation chamber 12. Due to the processing method of raw pressing of wolfberries, the seeds and peels of the fruit peels and leaves screened out by the primary sieve 4 cannot be separated. Therefore, the fruit residue screened out by the primary sieve 4 contains a large number of seeds. In order to improve the recovery rate of these seeds, this application sends them to the drying equipment 6 for drying. The drying equipment 6 can be a hot air drum dryer. After drying, the peels and seeds maintain a certain connection state through moisture. During the drying process, the moisture of the peels and seeds gradually dissipates, and the tissue connecting the peels and seeds shrinks and dries due to water loss, thereby weakening the connection force and making it easier for the seeds to fall off the peels.

[0017] In a preferred embodiment, the top of the separation chamber 12 is provided with an air output pipeline and a fruit pomace outlet. The fruit pomace outlet is connected to an air separator 13. The air separator 13 separates the fruit seeds and other impurities for a second time. The fruit seeds are sent back to the vibrating screen 3 for rework, while the other impurities are sent to the next process.

[0018] In a preferred embodiment, the separation chamber 12 is equipped with a baffle. The air blown out by the venturi tube 10, along with the fruit residue, hits the baffle, separating the seeds from the peel or other attached carriers. The dried peel and seeds are accelerated by the air conveyor and the venturi tube 10 and impact the baffle. Upon impact, the peel and seeds break at the junction, thus better separating the seeds and peel. The seeds are then separated by the air separator 13, and the seeds are returned to the vibrating screen 3 for further processing and separation, while the impurities are sent to the next process.

[0019] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0020] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
