In addition, the company's development and production of a flow drying device "PJ Finikesi" also made a very good market evaluation, the main features are: continuous drying can be achieved without storage. Using SUS304 material, the sanitary structure is safe and suitable for food material processing. Good thermal efficiency, high product quality, no burnt, discoloration. The price is low. Not long ago, Marukoya Co., Ltd. has used it to continuously treat bean curd residue.
The “Micro Spray Dryerâ€, a spray drying device developed and produced by Fujisaki Electric Co., Ltd., has achieved a new drying technology that can produce droplets of one micron at a time to be spray-dried into finished microparticle powders.
In the conventional spray-drying apparatus, although there are also experimental machines that take 1 μm droplets at a time, it is difficult to actually manufacture them. To solve this problem, the key technology adopted by the company is the four-fluid nozzle technology, which has been applied for patent rights in Japan, the United States, and Europe.
In general, a typical spray drying apparatus is a rotary atomizer pressurizing nozzle, which is a two-fluid nozzle using compressed air. Even a two-fluid nozzle with a small particle size can hardly spray a large amount of powder products of about 1 micron (1 μm). Now a four-fluid nozzle can be used to produce droplets with a particle size of 1 μm, and it is also possible to freely adjust and control the diameter. In addition, a different type of stock solution is mixed at the tip of the nozzle to complete the powdering operation.
Since a clean-type externally-mixed nozzle is used, there is no need to worry about the clogging of the nozzle with the adhering matter, and a long-time continuous spray operation can be realized while various spray amounts of the spray head are manufactured by changing the edge diameter.
The spray drying tester used in research and development can produce fine powdered products after a small amount of tests, and the same fine particles as the experimental machine can be obtained through an expanded scale of production. The sprayer is specially equipped with a glass window confirming the material spray. The experimental data is confirmed by the screen image and can also be printed out.
The advantage of atomization of the spray-dried product is that the drying time is short, and the temperature is low, and the deterioration of the color and flavor of the product is also small. At the same time, the process of directly preparing the powder product from the liquid material is simplified, and the energy saving and labor saving requirements are achieved. Moreover, the device itself has a compact structure, requires a small site area, and has low equipment and transportation costs.
The “multi-stage spray dryer systemâ€, a two-stage drying device developed and manufactured by Japan Powder Company, has no pipe loss structure, and has been obtained by selectively delaying the retention time of large-size particles in the hopper part of the lower part of the exhaust chamber. Drying effect: The height of the exhaust chamber is less than 50% of that of the conventional vertical nozzle spray dryer, which makes powder that can not be processed by the conventional model spray dryer because of its high cohesiveness and lack of liquidity This again results in a single-stage drying effect, so that the drying process is easily achieved. The dryer is a monolithic structure, and is mostly used by research institutes and small-scale production companies. It is suitable for small batches and multi-variety production. The advantages are: small setting site and low price; automatic cleaning for a short time; non-burning binary hot air heating method; changing the diameter of the hot air inlet and outlet pipes and adjusting the temperature due to the characteristics of different materials; Cyclone dust collector cooling finished products and many other features have been highly evaluated in the market. Such as Japan's Riken Vitamin Co., Ltd. Chiba plant has chosen this spray dryer for small batch production of a variety of products.
