1. Product Overview

1. Basic Equipment Information

  • Product Name: Home & Commercial Stainless Steel Multifunctional Mini Screw Oil Press Machine / Cold & Hot Dual-Mode Physical Edible Oil Expeller (Home Use Mini Palm Sunflower Olive Coconut Oil Press Machine Screw Household)
  • Product Models: ZYJ-868 (Standard Household Model) / ZYJ-888 (Commercial Heavy-Duty High-Torque Model)
  • Equipment Type: Continuous Screw Extrusion Physical Cold/Hot Oil Press
  • Market Positioning: Designed for home kitchens crafting infant nutritional oils (walnut, flaxseed oil), premium private culinary oils, live on-demand community pressing stands, restaurant specialty kitchens, and boutique farm agritourism retail.

Engineering & Manufacturing Highlights:

  • Full Food-Grade SUS304 Thickened Stainless Steel Construction: From the infeed hopper, external housing, and oil catch cup to the slag discharge tray, all product-contact surfaces are forged from certified SUS304 stainless steel. Resists corrosion from organic fatty acids, prevents discoloration over years of use, and cleans effortlessly with brushed satin finishes.
  • High-Frequency Carburized & Quenched Precision Screw & Barrel: The core extrusion screw rod undergoes specialized high-temperature metallurgical hardening, providing superior resistance to abrasive wear and extreme compressive thrust. The progressive pitch of the screw barrel applies multi-stage differential volume compression, thoroughly pressing hard kernels (walnuts, sunflower seeds, dried coconut) to deliver bone-dry, razor-thin residual oil cakes with zero seed leakage.
  • Pure Copper High-Torque AC/DC Motor with Optimized Airflow: Features a heavy-duty customized pure copper wire-wound motor delivering steady, continuous torque to prevent jamming under heavy seed loading. Equipped with an internal low-noise axial cooling fan and multi-louver heat vents to support hours of uninterrupted pressing without thermal degradation.
  • Microcomputer Self-Regulating Band Heater (Cold/Hot Dual Modes): Integrated with a wrap-around high-efficiency heating collar that preheats rapidly with precise temperature regulation. Operators can switch between "Unheated Pure Physical Cold Pressing" (preserving heat-sensitive enzymes and delicate omega-3s) and "Thermostatic Hot Pressing" (roasting seeds slightly to unleash intense nutty aromas and maximize extraction rates).

2. Core Functions & Operating Principles

The machine operates on Physical Progressive Volumetric Compression and Mechanical High-Shear Extrusion:

  • Infeed & Progressive Material Forwarding: Oilseeds gravity-feed from the top stainless steel hopper into the compression chamber. The rotating progressive screw pushes the seeds continuously along a narrowing helical channel.
  • Intense Cell Rupture & Oil Expulsion: As the channel volume contracts, immense shearing and mechanical pressure crush, tear, and rupture the cellular oil-bearing cavities, forcing virgin crude oil out through the micro-drainage slots along the bottom of the barrel.
  • Real-Time Oil-Slag Separation: Freshly squeezed crude oil trickles through the lower drainage ports into the oil cup through an ultra-fine stainless steel mesh filter. Simultaneously, dehydrated, hardened residual cake is continuously extruded out through the front annular discharge nozzle, achieving clean, automatic oil-slag separation in real time.

3. Core Value: Why Choose This Equipment?

  • Pure, Authentic Oil Free from Adulteration: Commercial supermarket blended oils frequently undergo chemical solvent extraction and harsh chemical bleaching that strip away essential micronutrients. Pressing seeds yourself guarantees 100% pure physical virgin oil with total ingredient transparency.
  • Extensive Botanical Seed Compatibility: One single machine handles over 30 distinct oil crops—from soft and hard nuts to seed grains and dehydrated fruit pulps. Switching ingredients requires only a quick rinse and wipe-down.
  • Ultra-Quiet, Compact & Plug-and-Play: Occupies a minimal countertop footprint, fitting comfortably in domestic kitchens or mobile food trucks. Runs on standard household 110V or 220V power with simple, single-button automated operation.

2. Standard Operating Procedures (SOP) & Production Workflow

To ensure maximum oil extraction rates, prolong the working life of the screw rod, and prevent feed blockages, strictly follow these procedures:

1. Raw Ingredient Preparation (Critical Success Factor)

  • Strictly Control Moisture Content (Dryness is Paramount):
  • NEVER feed wet, fresh, or moisture-laden ingredients directly into the machine! Freshly harvested peanuts or damp nuts cause the screw to slip inside the barrel, preventing pressure buildup and resulting in cloudy, unpressed mush.
  • Dryness Testing Standard: Peanuts should shed their skins cleanly when rubbed between fingers; walnuts should snap crisply; sesame seeds should rustle dryly. If ingredients are damp, toast them gently in a pan or bake in an oven/microwave for 2–3 minutes, then allow them to cool to room temperature before pressing.
  • Targeted Pre-Processing for Specialty Crops:
  • Coconut (Copra): Fresh coconut flesh cannot be pressed directly. Use matured, dehydrated coconut meat, diced into small cubes (approx. 5–8 mm / peanut size), and thoroughly dried before pressing.
  • Olive & Palm: NEVER feed whole olives or palm fruit with internal hard stones/pits! Rock-hard pits will jam and catastrophic crack the hardened alloy screw. You must destone the fruit manually or mechanically, utilizing only dried or partially dehydrated fruit pulp.
  • Walnut: Fully remove all hard outer wooden shells; feed only raw or roasted shelled walnut kernels.

2. Pre-Start Inspection & Preheating

  1. Place the unit on a flat, dry, and heat-resistant work surface.
  2. Verify Assembly: Ensure the screw rod is fully seated inside the motor drive socket, slide the barrel into position, and secure it with the quick-release lock pin or bolt.
  3. Connect the plug to a dedicated, grounded 110V or 220V power outlet.
  4. Preheating (Hot Press Mode):
  5. Turn on the "Heating" switch on the rear panel. Allow the barrel to preheat for 5 to 8 minutes until the heating element stabilizes at operating temperature (approx. 150°C–200°C / 302°F–392°F).
  6. Note: For raw cold pressing (e.g., flaxseed), keep the heating switch OFF. Note that cold pressing requires exceptionally crisp, dry seeds and yields slightly lower oil output.

3. Standardized Pressing Operation

  1. Initiate Motor Rotation: Press the "Squeezing / Forward" button. The motor will start rotating smoothly.
  2. Smooth Seed Infeed: Pour prepared dry oilseeds into the upper hopper. For the first few moments, feed small handfuls gradually until the front nozzle begins steadily extruding firm, dry cake strips. Once established, fill the hopper continuously.
  3. Oil Catching & Filtration: Place the stainless steel oil cup with its fine-mesh strainer directly beneath the barrel drainage slots. Golden crude oil will filter into the cup while fine pulp particles are caught on the screen.
  4. Anti-Jam Reverse Function: If foreign debris enters the chamber or over-feeding causes the motor to stall, immediately stop the machine and press and hold the "Reverse" button for 3 to 5 seconds to back the screw out. Clear the blockage, then switch back to forward rotation.
  5. Cycle Completion & Clear-Out: Once the hopper empties, let the motor idle for 1 to 2 minutes to completely purge remaining slag from the chamber, then turn off both the squeezing and heating switches.

4. Shutdown, Cleaning & Preventive Maintenance

  • Disassemble While Still Warm (NEVER Allow Residue to Cool & Solidify):
  • Critical Step: Put on heat-resistant gloves immediately after shutdown. While the barrel is still warm, pull the locking pin and slide the barrel and screw rod out together. (If left to cool completely, hardened oil cake acts like superglue, locking the screw inside the barrel and making disassembly extremely difficult.)
  • Washing & Drying: Wash the disassembled screw rod and barrel with warm soapy water and the included steel-wire tube brush. After cleaning, dry all parts thoroughly with a towel or dry heat, apply a thin coat of edible cooking oil across the metal surfaces to prevent oxidation, and reassemble.
  • Keep Motor Housing Dry: The main chassis houses the electrical motor and circuitry. NEVER immerse the main machine body in water or rinse it with running faucets. Wipe the exterior stainless steel casing clean with a damp cloth.

4. Frequently Asked Questions (FAQ)

  • Q: Can this machine genuinely extract oil from olives, coconuts, and palm fruit? What are the specific requirements?
  • A: Yes, absolutely, but due to their physical structure, strict pre-processing is required:
    1. Coconut: You cannot press fresh, watery coconut meat directly. You must use matured, dehydrated copra meat chopped into peanut-sized dice (5–8 mm), thoroughly dried before feeding.
    2. Olive & Palm Fruit: This machine uses a high-precision hardened screw; you must NEVER feed olives or palm fruit with whole hard stones/pits inside. Hard pits will jam or chip the screw. You must destone the fruit first, feeding only the dehydrated or sun-dried flesh under hot-press mode.
  • Q: Is the extracted oil ready to consume immediately? Why does fresh-pressed oil look slightly cloudy?
  • A: Yes, it is 100% edible immediately. Freshly extracted oil appears slightly hazy because it contains microscopic suspended botanical fibers and natural plant phospholipids—a hallmark of unrefined virgin oil. Simply let the freshly strained oil settle in a dark container for 12 to 24 hours; fine particles will precipitate naturally to the bottom, leaving crystal-clear, aromatic virgin oil on top.
  • Q: What is the practical difference between hot pressing and cold pressing? Which yields more oil?
  • A:
    • Hot Pressing (Heater Engaged): Heating seeds reduces oil viscosity and denatures proteins, enabling oil molecules to release freely. This delivers the highest extraction yield and the most intense roasted aroma (ideal for peanuts, sesame, and rapeseeds).
    • Cold Pressing (Heater Disengaged or Low Heat): Seeds are crushed at gentle ambient temperatures, fully preserving bioactive micronutrients, delicate antioxidants, and essential fatty acids without thermal alteration. The oil is lighter in color and taste (ideal for flaxseed, perilla seed, and infant walnut oils).
