Description

Technical Field

[0001] The invention relates to the technical field of spray drying sampling devices, in particular to a device and a sampling method for sampling in a spray drying tower. Background Art

[0002] Spray drying is a drying process in which the raw material liquid is dispersed into droplets by an atomizer and hot air (or other gases) is directly in contact with the droplets to obtain a powder or granular product. The raw material liquid can be a solution, emulsion or suspension, or a molten liquid or a paste. The dried product can be made into powder, granules, hollow spheres or pellets as needed. Instant coffee, milk powder, convenience food soups, etc. that are common in the food industry are products obtained by spray drying.

[0003] When spray drying is used, the liquid material must be dried first. During the drying process, the liquid material will become solid particles and fall down, and may also be adsorbed on the top of the sampling device. However, it is difficult for the existing drying spray tower to clean some particles adhering to the sampling device during use, which causes the material adhering to the sampling device to block the sampling device, making it difficult to collect the sample, thereby affecting the accuracy of the sampling.

[0013] A sampling method for a device for sampling in a spray drying tower, comprising the following steps:

[0014] S1: When in use, first connect the discharge pipe to the subsequent processing equipment, connect the feed pipe to the storage box, start the fan and water pump, and the annular block will absorb air from the outside when working, so that the gas is converted into hot air through the heater, and then enter the inside of the annular block through the air inlet pipe and the connecting pipe, and enter the inside of the main body from the air inlet at the bottom of the annular block to dry the material;

[0015] S2: When the water pump is working, it will extract materials from the storage box, so that the materials pass through the feed pipe and the discharge pipe to the inside of the feed funnel, and the fan will make it rotate, and drive the rotating shaft and the cross fixing frame to rotate, thereby driving the annular sprayer to rotate and spray;

[0016] S3: When the sleeve rotates, it drives the fixed plate and the vertical plate to rotate together, and drives the slide rail to rotate through the vertical plate, thereby driving the circular shaft to move up and down, and the circular shaft drives the annular scraper to move up and down to clean the inner wall of the main body;

[0017] S4: When the slide rail rotates and drives the circular shaft upward, it will drive the telescopic rod to rotate, and move the arc-shaped sliding block through the rotating plate, thereby driving the push plate to rotate, and pushing the pull plate to move downward will drive the connecting plate to move downward. When the connecting plate moves downward, it will drive the pressure plate to move downward, and push the cleaning roller through the pressure rod to clean the sampling box.

[0018] The present invention has the following beneficial effects:

[0019] (1) In the present invention, when the slide rail rotates and drives the circular shaft upward, it will drive the telescopic rod to rotate. When the telescopic rod rotates, it will pull the rotating plate and make it rotate. When the rotating plate rotates, it will drive the arc-shaped sliding block to move horizontally through the straight slot and the cylinder. When the arc-shaped sliding block moves horizontally, it will drive the push plate to rotate through the cylinder, and push the pull plate to move downward through the round rod. When the pull plate moves downward, it will drive the connecting plate to move downward. When the connecting plate moves downward, it will drive the pressing plate to move downward, and push the cleaning roller to clean the sampling box through the pressing rod, so as to avoid the material adhering to the sampling box during the spray drying process, thereby causing the round hole on the top of the sampling box to be blocked and the sample to be difficult to collect, which affects the accuracy of sampling.

[0020] (2) In the present invention, when the water pump is working, it will extract materials from the storage box, so that the materials pass through the feed pipe and the discharge pipe and enter the feed funnel. When the materials enter the feed funnel, they will contact the fan and push the fan to rotate. When the fan rotates, it will drive the rotating shaft to rotate, and drive the sleeve to rotate through the rotating shaft, thereby driving the annular sprayer to rotate, so that the materials rotate during spraying so that the sprayed materials are evenly distributed, avoiding the difficulty in obtaining representative samples due to the uneven distribution of materials and the drying state in the spray drying tower, resulting in the sampling results not being able to accurately reflect the situation of the materials in the entire tower, thereby affecting the accuracy of subsequent analysis and evaluation.

[0021] (3) In the present invention, when the sleeve rotates, it will drive the fixed plate to rotate together. During the rotation of the fixed plate, it will drive the vertical plate to rotate together. When the vertical plate rotates, it will drive the slide rail to rotate. Since the slide rail is arranged in a wave shape, when the slide rail rotates, the circular shaft sliding inside the discharge pipe will move up and down along the shape of the slide rail during the rotation of the slide rail. When the circular shaft moves up and down, it will drive the annular scraper to move up and down to clean the inner wall of the main body. There may be residues on the inner wall of the main body during the drying process. These residues may affect the representativeness of the sampling, so that the sample obtained cannot truly reflect the material state during the spray drying process. Cleaning the residues with the annular scraper can reduce this influence and make the sampling more representative.

[0022] (4) In the present invention, the push plate will drive the push-pull block to move downward in the process of pushing the pull plate to move downward, and the push-pull block will drive the extrusion plate to move downward in the process of moving downward. The extrusion plate will generate suction when moving downward, and the material passing through the sampling box from the outside will be sucked through the circular hole on the top of the sampling box, so that the material falls into the sampling bottle for storage. The negative pressure generated by the downward movement of the extrusion plate can absorb the material passing through the sampling box from the outside, so that the material can be quickly and effectively sucked from the tower into the sampling bottle, greatly shortening the sampling time.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
