Abstract
Description
Technical Field
[0001] This utility model relates to the field of starch equipment, specifically to a high-efficiency and energy-saving airflow drying system for modified starch production. Background Technology
[0002] Airflow drying refers to the rapid flow of heated air within a pipe. Wet materials enter the pipe and are carried towards the pipe outlet by the high-speed airflow. During this process, water vapor evaporates simultaneously due to convective heat and mass transfer. Because the material is thoroughly mixed by the high-speed airflow after entering the pipe, a cyclone separator is typically used at the pipe outlet to separate the gas and solid phases. Airflow drying generally takes about one second.
[0003] Currently, Chinese patent CN204944127U discloses a corn modified starch airflow drying device, which includes a hot air furnace, a feeder, a drying pipe, a cyclone separator I, an airlock, a material box, a fan, a cyclone separator II, and a bag collector. One end of the drying pipe is connected to the hot air furnace, and the other end is connected to the cyclone separator I. The feeder is installed on the drying pipe, located on the side where the drying pipe connects to the hot air furnace. The bottom of the cyclone separator I is connected to the airlock. A material box is located below the airlock. The cyclone separator I and the cyclone separator II are connected by a pipe. The bag collector is connected to the cyclone separator II by a pipe.
[0004] Although this type of corn modified starch airflow drying equipment adopts a negative pressure suction structure, which not only has high drying intensity, short drying time, and high thermal efficiency, but also a good working environment and low loss of corn modified starch, it often occupies a large area, which is not conducive to space utilization and has low efficiency. Summary of the Invention
[0005] One objective of this invention is to provide a high-efficiency and energy-saving airflow drying system for modified starch production, which has the advantages of effectively saving space and increasing efficiency.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A high-efficiency and energy-saving airflow drying system for modified starch production includes a machine body with a feed inlet. Below the feed inlet is a buffer tank, and below the buffer tank are two cyclone separators. A heating coil is installed on the outer wall of the buffer tank. A material distribution device is provided between the buffer tank and the cyclone separators. The material distribution device includes a distributor located below the buffer tank, with two outlets connected to the cyclone separators respectively. A solenoid valve is installed at each outlet of the distributor. Below the cyclone separators is a storage tank, and the storage tank is equipped with a recovery device.
[0008] By adopting the above technical solution, the buffer box can be temporarily used to buffer starch, and then the starch is distributed by the distributor and enters the cyclone separator through two outlets to separate starch and water vapor. Then it enters the storage box for temporary storage. The buffer box is equipped with a heating coil, which can effectively increase the temperature of the buffer box and improve the evaporation efficiency of starch.
[0009] Further feature: The cyclone separator is also equipped with a heater.
[0010] By adopting the above technical solution, the heater installed on the cyclone separator can further increase the evaporation during the separation process, thereby improving the evaporation efficiency.
[0011] Further configuration: The recycling device includes a material extractor located on the storage bin, and a one-way valve is provided between the material extractor and the storage bin. The outlet of the material extractor is connected to a distributor.
[0012] By adopting the above technical solution, the installed material extractor can effectively extract the starch from the storage bin back onto the distributor for re-drying.
[0013] Further feature: The bottom of the storage box is also provided with a discharge port.
[0014] By adopting the above technical solution, it is convenient for users to effectively remove the dried starch.
[0015] Further features: The storage box is also equipped with a sampling port, and the sampling port is also equipped with a threaded sealing cap.
[0016] By adopting the above technical solution, the sampling port can be conveniently used by users to take samples, thereby determining whether the drying degree of starch meets the requirements.
[0017] Further feature: The buffer box is also equipped with a temperature indicator.
[0018] By adopting the above technical solution, the temperature indicator provided allows users to easily monitor changes in the internal temperature.
[0019] In summary, this utility model has the following beneficial effects: it adopts a preheating method and effectively separates starch from water vapor through a cyclone separator, thereby ensuring the dryness of the starch. Furthermore, the parallel connection of multiple cyclone separators can better ensure production efficiency. Attached Figure Description
