27KW New Electric Steamer (Upgraded)

This is a completely upgraded version of our factory's previous model. It features a thickened dual water tank design with separate heating and water injection functions — the main tank handles heating while the auxiliary tank is a negative-pressure tank providing water injection.

The main tank has larger capacity. Tanks, connecting pipes, and fittings are all 304 stainless steel. Maximum single-batch capacity: 100 kg. Materials can be fully steamed through in just 20 minutes.

• Dual tank design — main tank heats, auxiliary tank injects steam
• 304 stainless steel tanks, pipes, and fittings throughout
• 3-level adjustable power: 9/18/27 KW
• Fully steams 100 kg in just 20 minutes
• Separated electrical/water sections for maximum safety
• Emergency stop switch included
• Quick-open maintenance access panel
• Dual drainage outlets — easy scale cleaning
• Independent float system — lower failure rate, quick repair access
• Lightweight at ~54 kg — easy installation

How the 27KW Electric Seed Steamer Works

The electric seed steamer machine (also known as an oilseed cooker or steaming equipment) uses electrical heating elements immersed in a water-filled primary tank to generate continuous steam. Water in the main tank is heated to boiling by 27 KW of power, adjustable in three stages (9/18/27 KW) to match different production volumes and seed types. The steam rises evenly through the 304 stainless steel cooking pot, penetrating the oilseed mass from bottom to top via natural convection. An auxiliary negative-pressure water tank automatically feeds fresh water into the main tank as steam is consumed, ensuring uninterrupted operation without manual refilling mid-batch.

Why is steaming critical before hydraulic pressing? Raw oil seeds contain oil locked within rigid cell walls. Applying dry pressure alone yields only partial extraction. Seed steaming softens the cell walls, coagulates proteins, and reduces oil viscosity — three changes that dramatically improve oil release during pressing. For hard seeds like mustard, rapeseed, and soybean, a 20-minute steam-through cycle in this oilseed cooker raises moisture content to the optimal 8-10% range, increasing press yield by 15-25% compared to unsteamed seeds. The HN-ST-E achieves this in batches of up to 100 kg, with full steam penetration in approximately 20 minutes. The dual-tank design means the machine continuously produces steam without pause for refilling — a significant upgrade over single-tank competitors that must stop between batches. Safety features include separated electrical and water sections, an emergency stop switch, and independent float-level monitoring for each tank. At only 54 kg and 1100×700×1550 mm, it installs in most workshop layouts without modification.

Application Scenarios & Use Cases

Operation Tips & Best Practices

• Water quality matters: Use clean, low-mineral water in both tanks. Hard water causes scale buildup on heating elements, reducing efficiency and lifespan. If local water is hard, consider installing a simple water softener upstream.
• Startup sequence: Fill both tanks before powering on. Set to 27 KW for initial heat-up (approximately 15 minutes to boiling), then reduce to 18 KW for continuous production. Never run the seed steaming machine with an empty tank.
• Batch loading technique: Load seeds loosely — do not compact them. Steam needs free pathways to penetrate evenly. Over-packed batches result in under-steamed cores and over-steamed outer layers.
• Steam-through timing: For most oil seeds (mustard, rapeseed, soybean), 20 minutes achieves full steam penetration. Monitor the steam vent — when steam exits uniformly from all sides, the batch is ready.
• Power level selection guide: Use 9 KW for small batches (under 50 kg) or delicate seeds. Use 18 KW for standard production. Reserve 27 KW for maximum throughput or initial heat-up only — continuous 27 KW may over-steam the outer layers.
• Scale removal: Drain both tanks weekly via the dual drainage outlets. For heavy scale buildup, fill with diluted food-grade descaling solution, heat to 60°C for 30 minutes, then drain and rinse thoroughly.
• Float system check: The independent float mechanism controls water level in each tank. Verify float movement monthly — a stuck float can cause tank overflow or dry heating element failure.
