Description

Technical Field

[0001] The invention belongs to a food processing machine for processing vegetables and fruits. Background Art

[0002] The processing methods using fresh vegetables and fruits as raw materials include the traditional process of stewing and steaming,

[0003] Food products represented by Chinese invention patent application number "201610163817.x" propose a process requirement of first washing fresh vegetables and fruits and making them into a fully ground and fine pulp, and then steaming the pulp over high heat for 2 minutes. The specific pulp steaming conditions are to steam the pulp placed in a container for two minutes and then take it out and cool it to a fermentation temperature, so that the pulp enters the fermentation state.

[0004] In view of the different scales and outputs of the main manufacturers engaged in the processing of fresh vegetables and fruits, including small and medium-sized food processing industries that purchase vegetables or agricultural product producers and sellers directly from farmers and large and medium-sized food manufacturers with large-scale machine assembly line production lines, the existing commercially available food processing machines for stewing and steaming vegetables and fruits do not have efficient continuous combined operation food processing machines specifically for the above-mentioned 2-minute stewing and steaming process. Summary of the Invention

[0005] The object of the present invention is to overcome the above-mentioned defects of the prior art and to provide a high-efficiency food steamer which is specially used for steaming vegetable slurry or fruit slurry for 2 minutes.

[0006] The technical solutions for achieving the technical objectives of the present invention are as follows:

[0007] The vegetable and fruit paste stewing and steaming apparatus of the present invention includes A. a multi-layer vertical type; and B. a tunnel pit type. The lower part of type A includes a boiler and a boiling water steam generator for heating the same, and the upper part is a stewing and steaming pot with a multi-layer horizontal circular shallow disc for holding the paste and supported on the side wall of the pot body by a bracket. The pot cover is provided with a narrow arc-shaped paste inlet with an appropriate opening, and the paste falls into the feeding area of ​​the disc from the upper feeding hopper. The center of each disc has a rotating vertical shaft, which is driven to rotate by a gear driven by a motor under the central bottom of the bottom disc. The vertical shaft is provided with multiple layers and multiple rows of paste push rods in each row, which are supported on the plane of each disc by a plurality of or a plurality of pairs of thin and narrow rollers and rotate forward in the same direction and aligned with the upper surface of the disc. Each row of push rods is connected to each other by several thin and tough stainless steel bars to form a solid and stable rotating body. Each push rod has a rectangular cross-section, with a thickness or height of about 1 cm or more and a horizontal width of up to several cm. Pairs of small rollers are installed inside it. Horizontal scrapers for the slurry are fixedly installed above and below the rear of each push rod, almost touching the surface of the disc. These scrapers move synchronously with the rod body and move upward and downward. These two scrapers are used to dynamically scrape downward the slurry above the push rod and to smooth out blockages on the disc surface, allowing the slurry to be evenly spread shallowly on the disc and heated by steam from all directions.

[0008] Each fixed disc plane is equipped with a feed area where the slurry falls and a discharge area with a long arc-shaped open space behind the feed area. When the slurry is pushed to the discharge area by the continuously rotating push rod, it immediately falls down to the feed area of ​​the next disc until it falls into the discharge port of the lowest layer. The outer head of the push rod is forward-facing, and the middle section is in a backward arc shape. Its shape matches the discharge area so that the slurry of different radial distances on the disc can be pushed and dropped at the same time. The upper feed area is located before the discharge port of the lower layer.

[0009] Type B is a steamer in a tunnel cellar that steams slurry of about 1 cm or thicker in a large box that is easy to move in and out and is placed on multiple rows of horizontally arranged and relatively circulating slurry conveyor belts on a plane for 2 minutes and then takes it out. The slurry can also be spread in a large box on a horizontal conveyor belt that circulates in multiple layers in an upper and lower manner. The slurry box is moved or spread on a horizontal mobile conveyor belt in time and is removed from the horizontal conveyor belt in time after 2 minutes. At each moment, several upper layers are moving horizontally at the same time. When they reach the end point, each layer of conveyor belt will reverse to its lower position in succession and return to the starting point. The slurry is steamed on the conveyor belt, whether it is in the upper or lower horizontal position.

[0010] Graphic Description

[0011] Attachment Figure 1 It is a three-dimensional schematic diagram of the structure of a multi-layer vertical tank-type stewing and steaming device;

[0012] Attachment Figure 1 "1" is the outer shell of the tank-type steamer; "2" is the tank cover; "3" is the feed inlet, the slurry comes from the hopper above, and the slurry flows downward from multiple places and is spread on the feed area "4" of the disc; "5" is the slurry push rod, its root is installed on the vertical shaft "6", and several or several pairs of narrow rollers are provided along the push rod body. For example, on the topmost disc "7", it moves forward as the vertical shaft "6" rotates: the vertical shaft "6" is driven to rotate by the lowest motor through the gear, and its vertical shaft "6" has an upper end, which passes through each disc upward until it is connected to the inner hole of the bearing on the lower surface of the tank cover "2"; "8" is a disc below the disc "7". The discharge port or the discharge area of ​​the lowest disc is also curved to match the shape of the push rod "5" for easy discharge or discharge; "9" is one of the horizontal brackets extending from the inner surface of the tank shell "1" to support each layer of disc. The spatial position of the bracket is also the flow space of the steam in the tank, just like the space between the upper and lower discs. After the slurry enters the tank, it undergoes 2 minutes of steaming during the 2-minute movement time in the tank and then moves to the discharge area of ​​each steaming unit composed of multiple steaming disc layers to complete the steaming operation process; the above-mentioned parts should be made of food-grade materials such as stainless steel, which are sturdy and durable and suitable for continuous operation and cleaning and maintenance.

[0013] Effect:

[0014] From the top tank lid inlet, batches of several kilograms or more of slurry are continuously and simultaneously laid down onto the inlet area, which matches the length and curvature of the push rod. The rod length ranges from tens of centimeters to over one meter. Each batch of slurry is fed in every few seconds, then steamed for two minutes while moving before flowing out of the bottom outlet. Using several steamers in this way, the hourly output of slurry can reach tens of kilograms, hundreds of kilograms, or even several tons. The larger the diameter of the steaming tank, the longer the push rod, and the faster the movement, the greater the processing output. Several layers of material trays can form a steaming unit, which is composed of an upper inlet and a lower outlet. Each batch of slurry entering the disc-shaped material tray receives a two-minute steaming time before flowing out to the slurry collection bucket below. The more layers there are, the faster the slurry moves on each layer, so that it can reach the bottom outlet just at the end of the two minutes according to the operation settings.

[0015] Vegetables and fruits are both local and potentially internationally traded commodities. The scale of producers who make pulp from fresh vegetables and fruits ranges from small to small, even to small farmers. The multi-layer vertical and tunnel-cellar-type 2-minute dedicated steamers for vegetable and fruit pulps of the present invention meet the quality preservation requirements of fresh vegetables and the need for rapid, automated, and efficient processing. The operator continuously feeds the pulp produced in the previous process into the upper layer of each Type A or Type B steamer unit, which is set according to the 2-minute steaming time requirement. Over the entire 2-minute period, each batch of pulp is pushed forward on the material tray by a push rod and flows from the upper layer to the lower layer and then into the material barrel at the discharge port. Example

[0016] Operators of stewed pulp with an hourly production capacity of tens to hundreds of kilograms or more than tens of tons can use one or several Type A multi-layer vertical or Type B tunnel pit stewing steamers of different sizes. During continuous operation, they should pay attention to maintenance to prevent blockage. Producers and traders of vegetables and fruits can collect and store vegetable and fruit raw materials nearby and carry out continuous processing from pulp to semi-finished products and finished products, so as to meet the needs of markets near and far.
