It delivers conveying capacity from 350L\/h to 3000L\/h across four models (QVC-1 to QVC-4) with food-grade stainless steel construction and GMP-compliant design. Ideal for tablet press feeding, capsule filling machine material transfer, and dry granulator powder dosing in pharmaceutical manufacturing and food processing facilities.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThis pneumatic vacuum conveying system operates by utilizing compressed air passing through a vacuum generator to create high vacuum for material handling, eliminating the need for mechanical vacuum pumps and providing maintenance-free operation. When compressed air is supplied to the vacuum generator, it creates negative pressure forming a vacuum airflow that draws material into the suction nozzle, creating a material-air mixture transported through the conveying tube to the feed hopper. The integrated filter separates material from air completely, and once the feed hopper is full, the controller automatically cuts off air supply causing the vacuum generator to stop while the hopper discharge valve opens automatically to discharge material into the machine's process hopper.\u003c\/p\u003e\n\n\u003cp\u003eThe Keypack Intelligent (Kunbupack) industrial vacuum conveying equipment features automatic filter cleaning via solenoid-controlled pulse-jet valve using compressed air, ensuring continuous operation without manual intervention for filter maintenance. The vacuum conveying system is automatically activated when preset time elapses or level sensor issues a feed signal, with conveying capacity highly dependent on conveying distance and material characteristics. This auxiliary powder conveyor offers numerous advantages including simple structure, compact size, maintenance-free operation, low noise levels, convenient control, elimination of material static electricity, and full compliance with GMP standards for pharmaceutical and food-grade applications.\u003c\/p\u003e\n\n\u003cp\u003eThe high vacuum generated by the vacuum generator ensures conveyed materials are free from stratification, guaranteeing uniformity and consistency of blended material composition critical for pharmaceutical formulations and food products requiring precise ingredient ratios. The anti-clog vacuum feeder design prevents material bridging and ensures smooth powder flow, particularly valuable for cohesive powders, fine granules, and materials prone to compaction or static buildup during pneumatic transport.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable class=\"specs-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eQVC-1\u003c\/th\u003e\n\u003cth\u003eQVC-2\u003c\/th\u003e\n\u003cth\u003eQVC-3\u003c\/th\u003e\n\u003cth\u003eQVC-4\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConveying Rate\u003c\/td\u003e\n\u003ctd\u003e350L\/h\u003c\/td\u003e\n\u003ctd\u003e700L\/h\u003c\/td\u003e\n\u003ctd\u003e1500L\/h\u003c\/td\u003e\n\u003ctd\u003e3000L\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHopper Capacity\u003c\/td\u003e\n\u003ctd\u003e1.1L\u003c\/td\u003e\n\u003ctd\u003e6.0L\u003c\/td\u003e\n\u003ctd\u003e12L\u003c\/td\u003e\n\u003ctd\u003e42L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAir Consumption\u003c\/td\u003e\n\u003ctd\u003e180L\/min\u003c\/td\u003e\n\u003ctd\u003e360L\/min\u003c\/td\u003e\n\u003ctd\u003e720L\/min\u003c\/td\u003e\n\u003ctd\u003e1440L\/min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAir Supply Pressure\u003c\/td\u003e\n\u003ctd\u003e0.5-0.6Mpa\u003c\/td\u003e\n\u003ctd\u003e0.5-0.6Mpa\u003c\/td\u003e\n\u003ctd\u003e0.5-0.6Mpa\u003c\/td\u003e\n\u003ctd\u003e0.5-0.6Mpa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimension (Φ mm)\u003c\/td\u003e\n\u003ctd\u003eΦ140×626\u003c\/td\u003e\n\u003ctd\u003eΦ213×622\u003c\/td\u003e\n\u003ctd\u003eΦ290×852\u003c\/td\u003e\n\u003ctd\u003eΦ420×1208\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eSystem Configuration\u003c\/h3\u003e\n\u003ctable class=\"specs-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eVacuum Generation\u003c\/td\u003e\n\u003ctd\u003eCompressed Air-Driven Vacuum Generator (No Mechanical Pump)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial Separation\u003c\/td\u003e\n\u003ctd\u003eIntegrated Filter with Complete Air-Material Separation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilter Cleaning\u003c\/td\u003e\n\u003ctd\u003eAutomatic Pulse-Jet Valve with Solenoid Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDischarge System\u003c\/td\u003e\n\u003ctd\u003eAutomatic Hopper Discharge Valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl System\u003c\/td\u003e\n\u003ctd\u003eAutomatic Activation via Timer or Level Sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial Construction\u003c\/td\u003e\n\u003ctd\u003eFood-Grade Stainless Steel, GMP Compliant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperation Mode\u003c\/td\u003e\n\u003ctd\u003eClosed-Loop Dust-Free Conveying\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplicable Materials\u003c\/td\u003e\n\u003ctd\u003eSmall Granules, Powders, Pharmaceutical Ingredients, Food Powders\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eApplication Areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePharmaceutical Industry - Tablet Press Powder Feeding:\u003c\/strong\u003e Pneumatic vacuum conveying system for pharmaceutical powder pneumatic transport from storage containers to tablet compression machines, delivering dust-free granule transport of API powders, excipient granules, and pre-blended tablet formulations.

Unlike mechanical conveyors where vibration and material flow can cause particle segregation based on size or density, this closed-loop powder conveying system maintains homogeneous mixture throughout pneumatic transport. This stratification-free conveying is essential for tablet press feeding where blend uniformity directly impacts tablet weight variation and API content uniformity, as well as for food applications requiring consistent flavor profiles and nutritional content.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e4.
