Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized vacuum conveyor manufacturer and custom vacuum conveyors designer of various kinds of conveyors, belts, pulleys, bearings, rollers, bushings and so on. Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

Problem:A major pharmaceutical company came to HAPMAN for assistance in providing them with a vacuum conveyor system to meet their specific requirements. It was to take their finished product from a dryer and discharge it into a mobile bulk material handling system, which was scale mounted for precision metering and batching. The problem was that it needed to incorporate an efficient cleaning system which totally eliminated any possibility of cross-contamination with product change overs.
Solution:To accomplish this, HAPMAN engineered its MiniVac pneumatic conveying system with individually controlled spray wash ports placed throughout the interior of this material handling conveyor. This "self-contained" design allowed the customer the ability to reliably clean and sanitize the conveyor's interior without the need for timely external procedures. Further time saving enhancements included a side access door for quick filter cartridge change outs, and a clean-in-place rotary valve which allowed disassembly, cleaning and reassembly within minutes. The entire sanitary finish assembly was 304 stainless steel with sealed motors and controls rated for explosive atmosphere and wash down applications.

PPC pneumatic pharma conveyors from Volkmann were especially developed for all those applications, which require top quality materials, surfaces and characteristics of all parts, which come in contact with the conveyed materials. They are mainly used inside Pharmaceutical and Color/Lacquer industries because of their separator elements being built in a one-piece design – an optimum for such applications with frequent product changes, which require a quick reliable absolute cleaning of the Process machinery to prevent contamination of products. PPCs superior manufacturing quality and their gap-free design fulfils highest quality demands. Nevertheless, they are easily taken into pieces by hand without tools and can be cleaned quickly and can be sterilized.
The design is completely electrical conductive, free of gaps and doesn’t have any inaccessible spaces where the product might remain. PPC conveyors come with a huge butterfly valve at the discharge, which can be taken to pieces without tools.
PPC Vacuum Conveyors are offered as pre-configured units regarding the individual application. They are available in the diameters 170, 250, 315 and 450 mm. You can choose from different Pharma- or electrical-conductive filter systems (e.g. for the feeding of products into Zone 0 of reactors). Special coatings or clamp modules are available upon your request.
