Description

Technical Field

[0001] This utility model relates to an alkaline treatment mechanism for whole fresh fruit after enzymatic hydrolysis in fruit processing, belonging to the technical field of fruit processing equipment. Background Technology

[0002] The existing citrus fruit processing production method is to peel and segment citrus to obtain citrus slices, and then process them to obtain fruit pieces. For example, Chinese invention patent with authorization announcement number CN104366317B and authorization announcement date 20170616 discloses a citrus fruit processing production method. The production method is carried out according to the following steps: (1) Raw material pretreatment: Place the raw citrus slices in the citrus soaking tank and soak them under acidic conditions for 1-12 hours;

[0003] (2) Raw material cleaning: The orange slices pretreated in step (1) are lifted into the aeration cleaning machine by the lifting mechanism. The discharge port of the aeration cleaning machine is equipped with a discharge device, which consists of a box and a rotatable bristle roller inside the box. The cleaned orange slices are further cleaned by the bristle roller to remove filamentous impurities and are ready for use.

[0004] (3) Alkali treatment of raw materials: The orange slices cleaned in step (2) are lifted by the lifting mechanism into the alkali treatment tank system for alkali treatment;

[0005] (4) Thermal separation: After the alkali-treated orange slices are filtered to remove water, they are sent to a jacketed kettle with stirring for thermal separation. After the orange slices are put into the jacketed kettle, hot water at 90-95℃ is injected. The mass ratio of orange slices to water is 1:1. When the water temperature in the jacketed kettle reaches 48-50℃, stirring and heating are started. When the temperature reaches 70-75℃, heating is stopped. The stirring time for each batch is 7-10 minutes. When it is found that the rotation of the material in the jacketed kettle changes from fast to slow or stops, hot water is added. When the cysts turn orange-yellow or the orange slice cysts are completely separated, stirring is stopped and the material is discharged into a buffer tank for later use.

[0006] (5) Screening: The material in the buffer tank is conveyed to the vibrating screen through the chute for screening;

[0007] (6) Impurity removal: The fruit granules obtained by screening in step (5) are first passed through a dissolved air flotation fruit impurity separator to remove impurities, then through a grate hanging mechanism to remove ribs, and finally through a trough water method to remove pits.

[0008] (7) Light inspection, weighing, pre-heating, filling, sterilization, and warehousing.

[0009] The method of this invention has high production efficiency, good product controllability, and produces fruit granules with uniform quality and extremely low impurity content. However, it still has shortcomings: in order to maintain the integrity of the orange slices and improve the product yield, the peeling of citrus fruits requires very high precision and is all done manually, which limits production efficiency and makes it impossible to balance quality and efficiency. To address this, the applicant, after years of practical research, has proposed a whole-fruit enzymatic treatment method for fruit granule processing. This method utilizes bio-enzyme treatment technology to pre-treat the whole fresh fruit with enzymatic hydrolysis, replacing the peeling, raw material pretreatment, and raw material washing steps of the existing technology. The enzymatic hydrolysis treatment has good controllability, high production efficiency, and can guarantee both quality and efficiency. To this end, an enzymatic hydrolysis tank and an acid treatment mechanism for whole fresh fruit enzymatic hydrolysis were designed and developed to complement the whole fresh fruit enzymatic treatment method used for fruit processing. In production practice, after the acid treatment mechanism, the pH needs to be adjusted to the process parameter requirements, generally close to neutral or slightly alkaline. However, if it is directly introduced into the alkaline treatment environment, the acid-base neutralization will generate a lot of heat, affecting the quality of the fruit (including the integrity and color of the fruit). Therefore, a water neutralization and dilution treatment process is added before the alkaline treatment to lay the foundation for the subsequent mild alkaline treatment step. For the alkaline treatment step, this utility model has also further optimized the structure to match the efficient alkaline treatment of whole fruit after enzymatic hydrolysis. Utility Model Content

[0010] The present invention aims to provide a more optimized structure for the alkaline treatment mechanism after the enzymatic hydrolysis of whole fresh fruit for fruit processing, in order to complement the enzymatic treatment method for whole fresh fruit in fruit processing. The alkaline treatment mechanism has a reasonable structural design and is matched with the enzymatic hydrolysis process of fresh fruit, which can ensure the quality of raw materials and balance product quality and efficiency.

[0011] The technical solution adopted by this utility model to solve its technical problem is:

[0012] An alkali treatment mechanism for whole fresh fruit after enzymatic hydrolysis in fruit processing is characterized by comprising a controller, an alkali treatment tank, and a conveying mechanism. The conveying mechanism is arranged along the length of the alkali treatment tank and can slide cyclically relative to the alkali treatment tank.

[0013] The alkali treatment tank is equipped with a suitable pH sensor and temperature sensor. The pH sensor, temperature sensor, and drive motor of the conveying mechanism are all electrically connected to the controller. The conveying mechanism includes a conveying section located inside the alkali treatment tank and a lifting section that slopes upward from the end of the alkali treatment tank. The conveying section slopes upward at an acute angle relative to the alkali treatment tank from the feed end to the discharge end. A storage bin is provided at the tail end of the lifting section.

[0014] This utility model features a reasonable structural design and good practicality. After enzymatic hydrolysis in the enzymatic hydrolysis tank, the fresh fruit undergoes acid treatment and neutralization / dilution. It is then introduced into an alkali treatment tank (which contains a pre-prepared alkali treatment solution, typically water, with regulated temperature) through the material inlet. The fresh fruit is propelled through the alkali treatment tank by a rotating conveyor mechanism. The alkali treatment time is controlled based on the conveyor's rotation speed. At the rear of the alkali treatment process, a lifting section separates the fresh fruit from the alkali treatment solution. Therefore, the alkali treatment mechanism has a reasonable structural design, perfectly matching the enzymatic hydrolysis process of fresh fruit, ensuring high-quality raw materials while balancing product quality and efficiency.

[0015] Preferably, the conveyor belt of the conveying mechanism is mesh-shaped and has several receiving plates along its width. The receiving plates can flip back and forth relative to the conveying mechanism. The receiving plates slide with the transmission mechanism, causing the fresh fruit material to move within the alkali treatment tank. When in the lifting section, the receiving plates can fix the collected fresh fruit material, preventing the material from flowing back into the alkali treatment tank and causing over-alkali treatment.

[0016] Preferably, the alkali treatment tank has grooves or slide rails on both sides along its length, and the conveying mechanism has corresponding slide rails or grooves on both sides. Through the cooperation of the grooves and slide rails, the conveying mechanism slides cyclically relative to the alkali treatment tank under the action of the drive motor. This conveying structure allows for gentle and stable operation within the alkali treatment tank, avoiding large collisions between fresh fruits.

[0017] Preferably, the receiving plate has rotating shafts or shaft cavities at both ends, and the conveying mechanism has corresponding matching shaft cavities or rotating shafts on both sides. The receiving plate also has a rotation adjustment structure, which allows for the tilting adjustment of the receiving plate through the cooperation of the rotating shafts and shaft cavities. The tilting angle of the receiving plate can be adjusted as needed to accommodate different residence times of fresh fruit in the alkali treatment tank. When a shorter alkali treatment time is required, the receiving plate is raised to quickly remove as much of the processed material as possible. When a longer alkali treatment time is required, the receiving plate is lowered, and the material moves slowly to meet the required residence time for alkali treatment.

[0018] Preferably, the alkali treatment tank is equipped with an alkali treatment water circulation channel, which ensures that the alkali treatment water circulates continuously. This circulation ensures the water fully contacts the fresh fruit, achieving thorough alkali treatment and preventing stagnant water from affecting the treatment effect.

[0019] Preferably, the material inlet of the alkali treatment tank is also equipped with a control valve. The control valve controls the opening and closing of the material inlet using a double-door design. The control valve includes a left rotating shaft and a left control plate, as well as a right rotating shaft and a right control plate, which are rotatably connected to the left and right sides of the material inlet, respectively. Locking elements are provided on the left and right control plates, either individually or between them. This enables intermittent neutralization and dilution treatment, facilitating intermittent operation.

[0020] Preferably, the conveying mechanism is a stainless steel mesh conveyor belt with drainage holes, and the drive motor of the conveying mechanism is a servo motor, thereby controlling its rotation speed and the alkali treatment time of the fresh fruit.

[0021] Preferably, the rotational speed of the conveying mechanism is 0.4-0.6 m / min.

[0022] Preferably, the alkali treatment tank is equipped with an automatic drainage mechanism and a water replenishment mechanism in parallel, which are connected to the alkali treatment water tank and the water replenishment water tank respectively through pipelines with control valves, and the control valves are electrically connected to the controller.

[0023] Preferably, the controller is a PLC controller and is electrically connected to an alarm device, which is an audible alarm and / or a visual alarm.

[0024] The beneficial effects of this utility model are:

[0025] This utility model features a reasonable structural design and good practicality. After enzymatic hydrolysis in the enzymatic hydrolysis tank, the fresh fruit undergoes acid treatment and neutralization / dilution. It is then introduced into an alkali treatment tank (which contains a pre-prepared alkali treatment solution, typically water, with regulated temperature) through the material inlet. The fresh fruit is propelled through the alkali treatment tank by a rotating conveyor mechanism. The alkali treatment time is controlled based on the conveyor's rotation speed. At the rear of the alkali treatment process, a lifting section separates the fresh fruit from the alkali treatment solution. Therefore, the alkali treatment mechanism has a reasonable structural design, perfectly matching the enzymatic hydrolysis process of fresh fruit, ensuring high-quality raw materials while balancing product quality and efficiency.
