ISTANBUL, TURKEY — Imas introduced the Multiplexa plansifter (MQA) to meet high-capacity requirements in flour mills, with models available for up to 10 passages.

With significant design improvements, the MQA offers increased reliability, performance, sanitation and insulation.

The Imas research and development team used the latest finite element analysis (FEA) virtual modeling technology for behavior analysis on plansifters and to measure the performance with simulation of real operating conditions.

Various validation tests were carried out with prototype sifters at the manufacturing plant (strain gauge, acceleration, and tension points etc.) to verify the performance under the actual load.

Multiplexa offers non-stop and trouble-free operation thanks to its strong drive system. The weight chassis of the drive system is made of a three-layered steel sheet, in order to provide high durability against excessive vibrational loads. Also, balance springs are used on the top and bottom of housings and ball bearings, which balance and distribute the operational load, and provide a safe operation.

It is equipped with a central lubrication system for bearings in the drive system, which provides ease and functionality in the periodic maintenance operation.

The traditional manufacturing method of a plansifter chassis is to use welding in joints, which may result in cracks, wear, and tear over time. The “no welding” design of the new Multiplexa plansifter helps eliminate standardization problems by welding during manufacturing.

Special aluminum extrusion profiles and cast-iron top/bottom frames of the plansifter are connected to each other with a special screwing technique. This structure provides geometric precision, advanced insulation properties, and extended long-term durability for the new Multiplexa, as well as easy sieve replacement.

The new Multiplexa plansifter’s isolation thickness in passage walls and doors has been increased from 5 mm up to 14 mm. This provides optimal thermal insulation in the plansifter and prevents high internal temperatures, condensation, and food safety related risks accordingly.

The plansifter provides sanitary conditions with its increased insulation, as well as excellent impermeability against microorganisms and similar hygiene problems.

All interior walls in contact with the product can be covered with stainless steel insulation (optional), which significantly reduces condensation. This is a perfect solution for B1- B2 passages under high ambient humidity and temperatures.

The distance between the plansifter passage walls and sieve boxes is increased by around 40% (from 45 mm to 63 mm) in order to ensure smooth product flow and better sanitary conditions in the plansifter.

All internal corners of passage walls, doors, and tension boxes of the plansifter are rounded with a wide radius. This prevents product adhesion or accumulation, contamination, molding, etc. risks, and provides better sanitation.

Laminated chipboard passage doors are still used by many manufacturers; however, they can be deformed easily over time due to humidity in the working environment. The new Multiplexa has stainless steel coating on passage doors, along with an increased isolation thickness.

Industrial type leakproof rubber sealings are used on passage doors, which also can be easily replaced.
