A cartridge filter 7 is vertically movably placed in a processing vessel 1 having a cylindrical profile. An ultrasonic washer 55 is fitted to the lateral wall 3a of the spray casing of the processing vessel 1. Washing liquid 56 is injected into the processing vessel 1 and the filter 7 is moved downward and immersed in the washing liquid 56. The washer 55 is activated under this condition to wash the filter 7. Since the washer 55 is arranged near the filter 7, the ultrasonic oscillation is easily transmitted to the filter 7 to efficiently remove the foreign objects adhering to the filter 7. Thus, with this arrangement, it is possible to wash the filter 7 in the processing vessel 1 without removing the filter 7 from a fluidized bed apparatus. In a filter washing apparatus 101, a cartridge filter 103 is contained in a processing vessel 102 and immersed in washing liquid 110. The filter 103 is rotatably suspended below an upper lid 104 by means of a retainer 107a, 107b, a rotary joint 108 and a filter anchoring knob 111. Then, it is washed in the washing liquid 110 as it is driven to rotate by a jet flow 144.

A rotating drum 3 has ventilation sections 6 that can ventilate the inside of the drum and the outside of the drum in the coating processing. To the ventilation sections 6, a panel unit 41 having arranged therein plural hollow pipes 42 through which cold water passes is attached. The hollow pipes 42 are fixed to a base plate 44 in parallel with each other, and a gap “G” is provided between the adjacent pipes. The base plate 44 is provided with a communication hole 45, and the hollow pipes 42 are so arranged as to face the communication hole 45. To both ends of the hollow pipes 42, charge/discharge collecting pipes 46a and 46b are fixed. In the coating processing, cold water is arbitrarily supplied to the hollow pipes 42 through the charge/discharge collecting pipe 46a to cool the drum 3 so as to bring about the temperature difference between the inside of the drum and processing objects, which can prevent coating base materials from adhering to the inside of the drum.

In a particle measurement device 1 for a powder or granular material processing apparatus, powder or granular material is introduced into a drawing tube 3, which is formed to be projected from the inside of the granulating vessel 2, by injecting high pressure gas from the inside of the granulating vessel 2, so as to capture it with adhesive film 6. The captured powder or granular material is photographed, and, based on the obtained image information, information on the powder or granular material within the granulating vessel 2 is obtained. An air inlet 4, which is communicated with the drawing tube 3, is provided in the drawing tube 3 in the neighborhood of its end portion 3b on the side of the outside of the granulating vessel 2. Through this air inlet 4, gas having higher pressure than the inside of the granulating vessel 2 is introduced into the drawing tube 3. By this, in the particle measurement device for the powder or granular processing apparatus, effects of remaining powder or granular material and flow out of the powder or granular material are removed, and grain size etc. are measured with high reliability.
摘要:
Processing vessel (1) is formed by overlaying a filter casing (2), a spray casing (3), a material container (4) and an air supply unit (5). Airtightnesses between respective units are maintained by airtight junctions (61 to 63). In the airtight junction (61), two seal portions (91 and 92) are radially provided, and U-seals (64 and 65) are contained. The U-seals (64 and 65) vertically move within seal grooves (67 and 68) through supply and exhaust of air to/from cylinder chambers (69 and 71), to thereby attain close contact with or detachment from flange (74). During particulate material processing, the airtightness of the seal portion (91) is maintained by the U-seal (64). During processing vessel washing, the airtightness of the seal portion (92) is maintained by the U-seal (65), to thereby prevent exposure thereof. Simultaneously, the U-seal (64) is raised, to thereby attain washing of the seal portion (S1) during the particulate processing.

A method of and an apparatus for sugar coating, the apparatus comprising: a rotatable vessel for containing a material to be coated; a baffle 9 movable independently of the rotatable vessel; a baffle mounting shaft 10 having a bent construction, for mounting the baffle 9 thereon; and a hydraulic cylinder for rocking the baffle mounting shaft 10 to displace the baffle 9. Load cells 17a and 17b for detecting the position of the baffle 9 relative to an accumulated layer M of a material to be coated are provided on the baffle 9. The load cells 17a and 17b serves for holding the position of the baffle 9 relative to the accumulated layer M of the material to be coated at all times, on the basis of a load imposed due to the presence of the contact with the material to be coated.

A centrifugal tumbling granulating-coating apparatus has a rotary disk rotated in the horizontal direction and a stator provided at an outer peripheral position of the rotary disk at a predetermined internal from the rotary disk. The rotary disk is formed therein with a peripheral edge portion having a circularly arcuate-shaped vertical cross-section erected from a flat bottom surface portion and curved upwardly. In the rotary disk, a height (H) from the bottom surface portion to an outer peripheral end is set at a value within a range of 0.30R.ltoreq.H.ltoreq.R to a radius of curvature (R) of the peripheral edge portion, a width (W) of the peripheral edge portion is set at a value within a range of 0.07D.ltoreq.W.ltoreq.0.25D to a diameter (D) of the rotary disk and the radius of curvature (R) of the peripheral edge portion is set at a value within a range of 0.10D.ltoreq.R.ltoreq.0.25D to the diameter (D). A powder contact portion of the stator is formed substantially vertically. By use of this centrifugal tumbling granulating-coating apparatus, a powder or granular material in more quantities per batch can be granulated and coated.
摘要:
A seamless capsule manufacturing device comprises a multiple nozzle 7 for ejecting liquid drops into hardening liquid 10 and a flow passage tube 11 for containing hardening liquid 10. The flow passage tube 11 has a deformation section 28 that includes an inlet part 25 and a formation tube part 28b showing a cross sectional area smaller than the inlet part 25. The liquid drops ejected from the multiple nozzle 7 into the hardening liquid 10 are once made to become spherical liquid drops 26 in a sol state at the inlet part 25. The liquid drops 26b are introduced from the inlet part 25 into the deformation section 28 while they are still in a sol state. As hardening liquid 10 is introduced from the inlet part 25 into the formation tube part 28b, its flow rate is changed and the liquid drops 26 are deformed due to the change in the flow rate to produce nonspherical seamless capsules SC. With this arrangement, it is possible to provide a method and a device for manufacturing high quality nonspherical seamless capsules with an enhanced level of productivity without requiring cumbersome parameter defining operations and delicate control operations.

摘要:
In a seamless capsule manufacturing apparatus that ejects a droplet from a nozzle into hardening liquid to manufacture a seamless capsule SC, tube passages which are synthetic resin tubes are provided as flexible sections between pumps and the nozzle. The vibration caused by the pumps is absorbed in the flexible sections and thus is not transmitted to the nozzle, whereby eyes or the like of the seamless capsule caused by vibration noises can be suppressed. Instead of a synthetic resin tube, a vibration absorbing block formed of an elastic member may be attached to the tube passages. Alternatively, a vibration absorbing unit, which is provided with a pad formed of an elastic member and for holding the tube passages, may be provided.
