Over 10,000+ customers' choice, Focus on screening industry 40+ years
In traditional food powder production workshops, the handling and cleaning of screening equipment are often headaches for operators and plant managers:
Heavy equipment – difficult to handle. Conventional linear screens are typically welded as a single integral structure – large, heavy, and immovable once installed. When workshop layout needs adjustment, production lines need relocation, or equipment requires factory repair, moving an integrated linear screen often requires forklifts and lifting equipment – consuming significant labour and time.
Complex structure – time‑consuming cleaning. The screen boxes of conventional screening equipment have welded dead corners, bolt protrusions, and other structural features where material can accumulate. During cleaning, operators must spend considerable time disassembling screens and internal components – cleaning often takes over two hours. In multi‑product changeover scenarios, this cleaning efficiency severely constrains production line flexibility.
Inconvenient sanitisation – hygiene risks. Food powders are consumed directly or indirectly – placing strict requirements on equipment hygiene and safety. Conventional equipment, due to structural limitations, cannot be thoroughly high‑pressure washed or immersion‑sanitised – leaving hygiene dead corners and increasing food safety risks.
The core design philosophy of Gaofu's SZF series modular food powder linear vibrating screen can be summarised in four words: modular and quick‑release.
The equipment features a modular design – with the screen box, feed hopper, discharge chute, vibration motors, and other main components designed as independent modules connected via quick‑release flange clamps and quick‑release locking mechanisms.
Modular discharge/feed components. The discharge chute and feed hopper are connected with quick‑release flange clamps – easy to disassemble for cleaning. When cleaning or component replacement is needed, simply release the clamps to separate the components without disassembling the entire machine.
Quick‑release screen structure. Screens use a clamp‑type fixing structure – removable and replaceable quickly without special tools. Entire screen decks can be removed and replaced within 3‑5 minutes.
Modular screen box. The screen box features a modular design – single or multiple screen decks (1‑5) can be flexibly configured according to production needs. Each module uses standardised interfaces for easy assembly and disassembly.
In simple terms: a conventional linear screen is a "single welded unit" – difficult to move and disassemble; Gaofu's modular linear screen is a "set of freely combinable building blocks" – move it where you need it, detach the component that needs cleaning.
The most immediate benefit of modular design is the convenience of equipment handling:
Modular disassembly – significantly reduced individual component weight. Integrated linear screens often weigh several tonnes – requiring forklifts or lifting equipment for handling. Modular design breaks the equipment into multiple independent modules – each with significantly reduced weight – allowing handling with ordinary forklifts or even manual effort. When workshop layout needs adjustment or production lines need relocation, the equipment can be quickly disassembled, moved separately, and reassembled – significantly shortening relocation cycles.
Quick‑release connections – more efficient installation and commissioning. Modules are connected via quick‑release flange clamps – disassembly and assembly require no special tools. Upon arrival at the site, operators can quickly complete assembly and commissioning – shortening production line deployment time.
Flexible adaptation to different production line layouts. Modular design allows discharge direction and feed position to be flexibly adjusted according to workshop layout. When production lines need modification or expansion, the modular linear screen can more flexibly adapt to new layout requirements.
In multi‑product changeover scenarios, cleaning efficiency directly determines production line flexibility and product quality stability. Gaofu's SZF series modular food powder linear vibrating screen incorporates multiple targeted design features for cleaning convenience:
Dead‑corner‑free structure – eliminating material residue. The screen chamber interior features seamless welding – no welded dead corners, no protruding bolts. All welds are finely ground – surfaces are smooth, and material cannot accumulate in gaps. After the screen frame is opened, high‑pressure washing and immersion sanitisation can be performed directly.
Quick‑release components – more thorough cleaning. Components such as the feed hopper and discharge chute are connected with quick‑release flange clamps – can be quickly detached. Each component can be cleaned independently – ensuring no residue. Screens use quick‑release clamps – can be removed and installed in minutes.
Significantly reduced cleaning time. Conventional integrated linear screens often require over two hours for cleaning. Gaofu's modular linear screen features a quick‑release structure – entire screen decks can be removed and replaced within 3‑5 minutes – cleaning time reduced from two hours to within half an hour.
While modular structure addresses handling and cleaning efficiency, another core requirement of food powder screening – hygiene and safety – must also be ensured through materials and construction.
304/316L food‑grade stainless steel construction. All food powder‑contact parts are made of 304 or 316L stainless steel – meeting food and pharmaceutical industry hygiene standards. Stainless steel is corrosion‑resistant, high‑temperature‑resistant, and finely polished for smooth, flat surfaces – reducing powder adhesion and facilitating water rinsing.
Rounded corners – no hygiene dead corners. For the food and pharmaceutical industries, hygienic stainless steel models with rounded corners – no dead corners, easy to clean. Equipment joint gaps are sealed – preventing contamination accumulation.
Fully enclosed structure – no dust emission. The equipment features a fully enclosed structure with food‑grade silicone seals – effectively preventing dust emission during screening. The fully enclosed screen box can be paired with a negative‑pressure dust extraction interface – further improving the workshop environment.
Compliant with GMP and food hygiene standards. The entire machine design complies with GMP standards – meeting the clean production requirements of the food and pharmaceutical industries. Internal and external surfaces are easy to clean with no dead corners – meeting food‑grade GMP requirements.
