Real Innovation Behind Every Machine

The equipment we supply is built on genuine, granted Chinese utility-model patents — not marketing claims. Each certificate below is a verifiable patent (search the patent number on any patent database). Because the certificates are in Chinese, we explain in plain English what each invention is and why it matters to you as a buyer. The specific machine models tied to each patent are shown beneath each one and are being added.

Quick-Locking Device for Pressure Tanks

ZL 2016 2 0204093.4China Utility Model PatentGranted 2016
What it is

A fast, tool-free locking mechanism that seals and releases the pressure vessel of an air-pressure oil filter.

Why it matters

Operators can open the filter to clean out filter cake in seconds instead of unbolting a heavy lid — cutting cleaning downtime while keeping a reliable seal under working pressure.

Built into our Air-Pressure Oil Filter. Specific model details for this patent — coming soon.

Movable Filtering Device for Air-Pressure Oil Filters

ZL 2016 2 0204130.1China Utility Model PatentGranted 2016
What it is

A removable multi-element filter assembly that sits inside the air-pressure oil filter.

Why it matters

The filter elements slide out for fast cleaning and replacement, and the multi-tube design increases filtering area — giving clearer oil, higher throughput and far easier maintenance.

High-Efficiency Oilseed Roasting Machine

ZL 2009 2 0217437.5China Utility Model PatentGranted 2010
What it is

An efficient roasting (seed-cooking) machine that heats oilseeds evenly before pressing.

Why it matters

Even, controlled roasting raises oil yield and develops flavour and aroma, while the efficient heating design uses less fuel — better yield and consistent quality at lower running cost.

Built into our Seed Roasting Machine. Specific model details for this patent — coming soon.

Patented Technology

Improved Seed Roasting Machine

ZL 2017 2 0331317.2China Utility Model PatentGranted 2017
What it is

An upgraded seed roasting machine with a refined heating drum and structure.

Why it matters

Builds on years of roasting know-how for more uniform seed preparation and easier operation — giving stable, repeatable pressing results.

Built into our Seed Roasting Machine. Specific model details for this patent — coming soon.
China Utility Model Patent certificate — Edible Oil Refining MachineClick certificate to enlarge
Patented Technology

Edible Oil Refining Machine

ZL 2013 2 0403367.9China Utility Model PatentGranted 2013
What it is

A machine that refines crude pressed oil — removing impurities, gums and colour — into clear, food-grade edible oil.

Why it matters

Turns raw pressed oil into clean, longer-shelf-life refined oil that meets edible standards, letting you offer a finished product rather than just crude oil.

Built into our Oil Refining Equipment. Specific model details for this patent — coming soon.
