Concentrator Screen

The thickener screen (also known as pressure wedge wire arc screen or wedge wire screen (Johnson screen)) is a core vulnerable spare part for gluten (vital wheat gluten / gluten protein) concentration and dehydration in corn starch production. Installed inside pressure wedge wire arc screens or centrifugal screens, it serves as key filtration media to realise solid liquid separation, concentration and dehydration of gluten slurry. Under operating pressure, gluten slurry flows at high velocity across the screen surface. Water and fine particles pass through slot openings for discharge, while concentrated coarse gluten fractions slide down the screen surface for collection, completing gluten concentration and washing workflows.

Dehydrator Screw

The screw press auger (also referred to as pressing auger / auger blade shaft) is the core rotating assembly of screw press dehydrators for corn gluten concentration dehydration workflows, and one of the most critical wear prone spare parts for dehydration equipment. Mounted inside dehydrator screen cylinder and driven by motor gear reducer unit. The auger with progressively decreasing pitch conveys gluten material forward while building gradually rising compressive force to squeeze water out through screen cylinder gaps, achieving mechanical dehydration of gluten slurry.

Rotary Drum

Rotary drum (vacuum filter drum / filter drum) is the core rotating component of vacuum drum filters used in corn gluten concentration dehydration; among the most critical main spare parts of dehydration equipment. It is a horizontally oriented cylindrical stainless steel shell covered with filter cloth, partially immersed inside feed trough and rotating slowly driven by main shaft. Drum interior is axially partitioned into multiple independent sector shaped vacuum compartments connected to vacuum system via end face distribution heads. Under vacuum suction effect, slurry moisture is drawn through filter cloth, gluten particles deposit as filter cake upon drum outer surface; completing continuous workflow of adsorption, dehydration and cake discharge.

Spiral Blade

Spiral blades (press blades / spiral segments) represent the most critical wear prone spare parts of corn gluten screw press dehydrators. These arc shaped plate components are welded onto dehydrator central shaft; directly contacting gluten material to realise conveyance and extrusion compression. As sub assembly elements of the auger, they suffer the most severe abrasive wear and require frequent replacement. After long term material extrusion and frictional scouring, blade outer edges and working surfaces gradually thin and deform, causing degraded dehydration efficiency and necessitating periodic replacement or hard facing weld repair.

Gear Reducer

Gear Reducer (geared motor / gear box) is core power transmission component for corn gluten concentration dehydration equipment (screw press dehydrator, vacuum drum filter etc.), key power system spare part. Installed between electric motor and working assembly (auger / rotary drum). Function: reduce motor high rotational speed (approx. 1450 rpm) down to process required low speed (10 30 rpm), meanwhile amplifying output torque to drive dehydrator internal rotating assemblies against material loading resistance.

Filter Belt

Filter belt (filter cloth belt / belt filter media) is core filtration element for corn gluten belt filter press dehydrators. It represents the highest consumption frequently replaced spare part among dehydration equipment components. It is an endless woven filter media tensioned across the complete roller set of filter press. Upper and lower filter belts sandwich gluten slurry between them and travel synchronously. Through sequential stages: gravity dewatering, wedge zone pre compression, low pressure dewatering and high pressure dewatering; water contained within gluten is gradually squeezed out passing through filter belt media, forming final dry gluten filter cake.

Belt Tracking Cylinder

Belt Tracking Cylinder (filter belt tracking cylinder / automatic deviation correction cylinder) is pneumatic actuator executing automatic offset correction for corn gluten belt filter press, key spare part governing filter belt running control. During belt filter press continuous operation, uneven belt tension, material distribution offset and roller surface wear will induce filter belt lateral mis tracking. Un corrected offset tracking will cause filter belt edge abrasion tearing, material spillage and secondary equipment damage. Receiving mis tracking detection signal, belt tracking cylinder drives tracking roller to perform left right swinging motion; real time adjusting filter belt travel trajectory and constraining belt operation along central reference line.

Cleaning Nozzle

Cleaning Nozzle (filter cloth washing nozzle / high pressure water jet nozzle) is key spray element for corn gluten belt filter press and vacuum drum filter equipment; performing high pressure rinsing toward filter belt / filter cloth media, classified as wear prone consumable spare part. Within dewatering workflow, fine gluten slurry particles progressively clog filter media openings; lowering water permeability and deteriorating dewatering results. After filter cake discharge, arrays of high pressure cleaning nozzles continuously rinse filter media, dislodging embedded gluten residues, restoring filter belt water permeability and securing reliable subsequent filtration cycle performance.

Tensioning Device

Tensioning Device (filter belt tension mechanism / automatic tension assembly) is mechanical hardware maintaining proper filter belt pre tension for corn gluten belt filter press; key spare part belonging to filter belt operating system. After long term cyclic stretching, endless loop filter belt gradually elongates and slackens. Insufficient belt tension will trigger filter belt slippage, wrinkling deformation, impairing dewatering efficiency and shortening filter belt service life. Tensioning device continuously exerts stable pre tension by pulling tension roller assembly travelling along linear guide rails; keeps filter belt operating within optimal tension range and compensates progressive filter belt elongation.

Bearing Housing

Bearing housing (mounted bearing unit / bearing support assembly) is key mechanical component deployed across corn gluten concentration dehydration equipment (belt filter press, screw press dehydrator, vacuum drum filter etc.), supporting diverse rotating rollers, auger shafts and rotary drums. It transmits shaft originated radial and axial loads onto equipment main frame; securing rotating components (roller / auger / drum) maintaining stable centre line position during rotary operation; lowering frictional resistance and suppressing vibration.
