Being adapted the big area heating way, its heat conducting area is large and its heat efficiency is high. Being installed stirring in the machine, it makes raw material in cylinder form the state of continuous circle inside the cylinder, so the uniformity to be heated of raw material is raised greatly. Being installed stirring in the machine, pulpinese, paste-like mixture or powder raw materials can be dried easy. It is an innovation horizontal batch-type vacuum dryer. The moister of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped by vacuum pump. The following raw materials from pharmaceutical industry, foodstuff industry, chemical industry and so on can be dried. Suitable for pulpiness, paste-like mixture or powder raw material. Thermal sensitive raw material having the requirement to dry at lower temperature. Raw materials that are easy to oxidize or explode and have strong irritative or toxic. Raw materials that need to recover solvent. Note: The evaporated amount of water its related to the characteristics of raw materials and the drying temperature. With renew products unceasingly, the related parameter will be exchanged, it does not announce in advance, pardon!Item Model Name Unit ZPD-500 ZPD-750 ZPD-1000 ZPD-1500 ZPD-2000 ZPD-3000 ZPD-5000 Working volume L 300 450 600 900 1200 1800 3000 Over in the cylinder Mm Φ 600 × 1500 Φ 800 × 1500 Φ 800 × 2000 Φ1000 × 2000 Φ 1000 × 2600 Φ 1200 × 2600 Φ 1400 × 3400 Stirring revolution Rpm 5-25 5-12 5 Power Kw 4 5.5 5.5 7.5 11 15 22 Design pressure of jacket Mpa ≤ 0.3 Pressure in the cylinder MPa -0.09— -0.096
