A mixing and blending method for powdered or granular material includes supplying pulsating vibration air into an airtight tank from a bottom thereof. An airtight tank having a porous bottom plate on which the material is stored is provided for the mixing and blending method. In the system pulsating vibration air is generated by periodically increasing and decreasing the amount of blowing air at a low frequency. Pulsating vibration air is introduced into the airtight tank from the bottom of the airtight tank so as to generate air flow going upward through the porous bottom of the airtight tank. As a result, powdered or granular material stored on the porous bottom plate in the airtight tank is uniformly mixed and blended in the airtight tank while continuously moving up and down as in a convectional manner.

Mixing method of powdered or granular material utilizing pulsating vibration air

A pulsating vibration air generator in which wave height, frequency and wave shape of the pulsating vibration air can be optionally modified and such pulsating vibration air can be periodically and continuously emitted. The pulsating vibration air generator has a valve chamber with an inlet port and an outlet port where a valve plug and a valve seat with a control opening are provided and a cam mechanism which moves the valve plug to open or close the opening of the valve seat, whereby positive or negative pulsating vibration air is emitted from the outlet port while pressurized air is supplied into the inlet port or air is sucked from the inlet port.

Pulsating vibration air generation means

A rotary-type tabletting machine with lubricant spraying means, wherein a turn table has plural penetrated holes comprising dies provided at fixed intervals in a ring-like arrangement, each hole is provided with a pair of punches above and under the hole, each pair of punches is rotated together with the turn table and execute piston operation so that tablets are continuously produced by compressing pharmaceutical material filled in the die. The rotary-type tabletting machine is provided with a spraying chamber with an upper open end for inserting an upper punch and enclosing the die when the turn table moves to a rotation position which is after a rotation position where a molded table is discharged and before a rotation position where pharmaceutical material is filled in the die. A spray connected with the spraying chamber sprays lubricant in the spraying chamber, and pulsating air generating means connected with the spraying chamber diffuses. The lubricant sprayed in the spraying chamber.

Rotary-type tabletting machine with lubricant spraying means

A pneumatic transport system for powdered materials for quantifying and pneumatically transferring powdered materials. When materials are fed above an inclined guide plate in a material feeder with its bottom opening closed by a valve plug, a slide damper is slid to divide the materials in the feeder vertically. An open space is formed under the inclined guide plate so that the materials aren't damaged when the slide damper is moved. When the valve plug is retracted, the materials under the slide damper are fed into a transport plug housed in a plug setting portion. The transport plug is pneumatically transported into a material discharge port by compressed air supplied by an air supply. After the transportation is finished, the transport plug is returned into the plug setting portion.

Pneumatic transport system for powdered materials

The present invention discloses a method and an apparatus for removing deposits from materials. By feeding unidirectional pulsating air pulsating while flowing in one direction, porous member (4), to materials (m) supplied from above the porous member (4) stretched laterally in a main body case (1A) of a removing apparatus main body (1), the deposits from the materials (m) are removed by the action of the unidirectional pulsating air. The apparatus comprises a removing apparatus main body (1) possessing a feed port (5) and a product outlet (11) disposed above a porous member (4) stretched laterally in a main body case (1A), and an air vibration generating device (30) for feeding unidirectional pulsating air pulsating while flowing in one direction, toward the porous member (4) from above the porous member (4).

Method and apparatus for removing deposits adhering on materials

The invention disclosed a method for cleaning a pipe in the inside comprising steps of inserting a pig into a pipe, and reciprocally moving the pig thereafter by aerial vibration to clean the inside of pipe. An apparatus for cleaning a pipe in the inside comprises a pig removably inserted into a pipe from an end side thereof and a vibration generating source for transferring the pig in reciprocal motion by means of aerial motion to clean the inside of pipe.
