A device for drying granules, such as those made from a plastic material. The device can have a spiral arrangement of one or more rotor blades on a rotor to propel process fluid through a sieve and separate the process fluid from granules by having sieve openings of a size smaller than the granules. The device can also have a fan wheel and a hollow rotor shaft to create an air flow and improve separation and drying of granules. The device enables reliable automated drying of granules using less energy than prior art devices.

An airflow drying device includes a granulated substance introduction portion, a dry process portion, and a product ejection portion. The granulated substance introduction portion includes a granulated substance inlet into which granulated substances are to be put, and a hot air inlet into which hot air is to be supplied. The dry process portion includes a loop pipe. The loop pipe is positioned laterally in a horizontal direction, and is able to dry granulated substances. The product ejection portion includes a cyclone collector where the granulated substances are collected after being dried through the loop pipe.

A centrifugal dryer that has improved throughput capacity resulting from the combination of a high angle agglomerate catcher with optional overflow, increased dewatering capacity, a cylindrical dewatering feed chute, a modified rotor design with positionally and structurally modified lifters in the feed and dewatering section, the drying and propagating section, as well as the pellet discharge section, and an efficient circumferential foraminous membrane.

A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flask 2 and a lower flask 3 includes a body that defines an opening in which a sand mold is to be molded. The body has at least one inlet 101 for introducing the mold sand into the opening. Two flanges 102 are extended from the body such that they are opposed to each other across the opening. Each flange has a through bore. The flask also includes engaging members for engaging an actuator in the outside of the flask such that a force or forces from said actuator could be transmitted to the flask. An upper flask 104 and a lower flask 105 are opposed to each other across a pattern plate 107. They are integrally assembled to make a flask unit by means of a pair of connecting rods 106 that are fitted in each bore.
