If you are researching YOSHAN coffee roasters before placing an order, this page gives you the direct facts: who they are, what the machines are actually like, what third-party verifications exist, and what real buyers have reported. No marketing copy — just the information a B2B buyer needs to make a decision.
Who Is YOSHAN?
YOSHAN (full name: Yoshan Inc.) is a coffee equipment manufacturer based in Shenzhen, China. Founded in 1990, they operate a 4,000 m² factory at Building B, Tongzhou Industrial Park, No. 162 Hedi Road, Guangming District, Shenzhen, Guangdong 518107.
They are the manufacturer behind the brands sold through:
- yoshanroasters.com — their own direct Shopify storefront (USA-facing)
- dongyicoffee.en.alibaba.com — their primary Alibaba trade account
- eacoffeesupplies.com — their North American distribution partner
- gohaiyangai.com — B2B wholesale inquiry channel (this site)
They produce three roaster series — SD (Probat-inspired), YS (Giesen-inspired), DY (classic traditional) — plus the EC-500G electric sample roaster, plus a full range of accessories including destoners, ESP smoke filters, afterburners and vacuum loading feeders.
Certifications: What Is Verified?
Third-party verification is the fastest way to assess a Chinese manufacturer. YOSHAN holds:
- CE — European Conformity. Mandatory for import into the EU and UK. Covers electrical safety, EMC (electromagnetic compatibility), and machine safety directive. CE-marked machines can be legally sold in 31 European countries without additional testing.
- SGS — SGS is one of the world’s largest inspection, testing and certification companies. SGS certification means a third-party inspector has physically audited the factory and/or product to the specified standard.
- ISO 9001 — Quality Management System standard. Requires documented production processes, traceability, and regular internal and external audits. Not just a paper certificate — it requires annual surveillance audits to maintain.
- RoHS — Restriction of Hazardous Substances. Required for products sold in the EU and UK. Confirms the machine does not contain lead, mercury, cadmium, hexavalent chromium, or specific flame retardants above legal limits.
- RS — Russian/CIS market certification, required for export to Russia and neighboring markets.
Certification documents are provided with every export order. If you need copies before ordering, request them in your inquiry.
Alibaba Standing: Only 5-Star SKA Verified Coffee Roaster Store
On Alibaba, YOSHAN’s dongyicoffee store holds 5-star SKA (Supplier Keyword Assessment) verified status — the only coffee roaster manufacturer on Alibaba with this rating. SKA verification requires demonstrated export history, buyer feedback, and response rate compliance audited by Alibaba’s team.
This matters because it is a third-party data point independent of the manufacturer’s own claims.
What Buyers Say
Across Alibaba reviews and independent forums, the consistent pattern in YOSHAN buyer feedback is:
- Build quality: machines are consistently described as well-built and heavy — which is expected for cast-iron drum machines. One US buyer reported roasting ~1,000 lbs of coffee with no mechanical issues.
- Packaging: multiple buyers note careful crating, with machines arriving undamaged even over long sea freight routes.
- Customer support: the after-sales team is described as responsive. YOSHAN maintains a 24-hour after-sales team and a CEO hotline.
- QC: each machine undergoes three factory inspections before shipping. YOSHAN reports zero complaints in the past three years.
The negative reviews found online relate to shipping tracking gaps (resolved on delivery) and in one case a delayed order. These are consistent with general risks of sourcing from China rather than YOSHAN-specific failures.
Machine Quality: What Sets YOSHAN Apart from Generic Chinese Roasters
There are dozens of Chinese coffee roaster manufacturers. Here is what YOSHAN does differently at a technical level:
- Siemens PLC (YS series): most Chinese manufacturers use generic Chinese PLC clones. YS series machines use genuine Siemens S7-series PLC — the same brand used in German industrial equipment. This means genuine spare parts availability worldwide.
- German dual thermocouples: YS series uses German-sourced dual thermocouples for simultaneous bean temperature and air temperature measurement. Single-thermocouple machines cannot distinguish between the two — a critical difference for specialty roasting.
- Cast iron drums: cheaper machines use thin stainless steel drums. YOSHAN SD and YS series use cast iron, which has 3–5x higher thermal mass. This means more even heat distribution and more stable batch-to-batch roast curves.
- Japanese ADDKA motors (YS series): four independent motors for drum, cooling plate, fan and stirring. Generic machines use one or two motors driving multiple functions through belts and gears — a common failure point.
- ±0.1°C temperature accuracy (SD Pro series): the fully-automatic SD Pro series holds temperature chasing accuracy to ±0.1°C. This is German roaster-level specification; most Chinese machines do not publish this figure at all.
Lead Time and Shipping
- Standard production lead time: 25–40 working days
- Large industrial machines (120 kg+): 60–120 working days
- Shipping: sea freight worldwide, DDP/CIF/FOB Shenzhen available
- USA West Coast: 18–22 days sea transit
- Europe: 28–35 days sea transit
- Australia/NZ: 22–28 days sea transit
OEM and Minimum Order
All YOSHAN models are available with OEM branding (custom logo, color, panel labels) from a minimum order of one unit. There is no batch MOQ for standard models. Custom specifications (voltage, gas type, drum size) require engineering discussion — contact the team with your requirements.
How to Inquire
The most efficient way to get pricing is to send: your country, the model you are interested in (or your batch size requirement), your preferred heating type (LPG/NG/electric), and whether you need accessories. The team responds within 24 hours with a detailed quotation including sea freight cost to your port.
