MSIPME-4-350 QUAD DRUM SYSTEM
The MSIPME 4-350 is one of the most flexible pulp high production moulding systems in the world, with options allowing the end user to process two similar products at the same time. Using a combination of robotic technology, centralized process control and monitoring system, it delivers one of the most repeatable pulp preparation and moulding machines available in the marketplace. The overall system is configured into three zones: pulp preparation, mould and transfer and lastly drying. The innovative use of servo motors for positioning, robotic transfer and tool change allows the end user to rapidly produce low volume; high mix moulded fibre products, with minimum down time for tool changes. With all the features combined, the end-user is able to quickly gain on the ROI as well as provide pulp moulded products to the market place very efficiently.
The pulp preparation is comprised of a vertical lift material loader, complete with a weight monitoring unit for dry weight measurement. The material loader is integrated onto a batch pulping unit; the pulper uses a PS or Volkes style de-fibering rotor combined with an extraction plate to blend the raw material with re-cycled water to create a 4-6% consistency (pulp to water). The pulp is then blended with water to further reduce the consistency to .75 to 1 percent via two servo driven pumps to ensure the proper ratio mix prior to entering the forming vat. All storage tanks (pulp, white water and head tanks) are manufactured using stainless steel for longevity, and have top mounted mixers to keep the material agitated prior to forming. Each tank is fitted with low and high level sensors for process monitoring prior to the moulding process. All piping is stainless steel tube or pipe with NPT fittings, and all control valves are constructed from stainless steel or brass as required.
The quad (4) headed rotary moulding system is designed to accommodate platens ranging from 19 1/2” (500mm) to incremental lengths of 48” (1200mm) 60” (1500mm) and 71” (1800mm). With this flexibility the system lends itself to be easily adapted to many low volumes; high mix moulded products. The moulding system features quick change tooling using precision locating devices as well as a static sealing system to ensure minimum vacuum loss during the “forming” process. MSIPME can customize the platens to meet your needs. All wetted components in the system are manufactured from stainless steel and all carbon steel is painted to customer specified colours. The moulding tank is a two tiered construction with a storage tank in the back which will supply pulp to an elevated shallow half barrel tank where the moulds will be introduced (the tank depth will be designed to accommodate the tallest product plus clearance). The pulp stock is circulated within the tank via a centrifugal pump; the shallow tank level is maintained with a “weir “type overflow. The system is designed with an automatic deckle and die wash system, where high pressure water is used to clean the moulding tool face after each cycle. A mineral oil spray system is located in the robot area for lubrication on demand of the transfer tool.
The moulded products (trays) are removed from the moulding dies via transfer tooling mounted to two 6 axis robots. The robots are infinitely programmable. Different products can be easily programmed to pick up and drop off in different positions with complete control of acceleration and deceleration this allows unique product patterns during the drying process, maximizing the useful area of the oven belt.
The Vacuum system will be designed as to industry standards with post and pre-separators to ensure maximum efficiency and water removal from the product when it is processed thus reducing the energy required in the dryer.
MSIPME will supply two drying systems (INFATROL) for the pulp moulding system. Each dryer will be a single pass system. The oven will be fired by natural gas with a maximum operating temperature of 175C-200C. The ovens will be comprised of one to three zones depending on the anticipated product mix for the control and temperature regulation. The belt will be made from a stainless steel flat wire mesh construction to allow for efficient air flow through the belt. Each drying system is designed to process maximum 150Kg/hr (dry weight) removing 600L/hr of water. (4:1 wet/dry ratio).
