If you are researching a YOSHAN coffee roaster before you place an order, this page gives you the direct facts a B2B buyer needs: who the company is, what the machines you are considering are actually like, which third-party verifications exist, what real buyers have reported, and how to check all of it yourself. No marketing copy for you to wade through — the information you would want from any supplier before a deposit, laid out so you can verify it.
Who Is YOSHAN?
Want to see how your machines are actually made? Take our Yoshan coffee roaster factory tour to see the build process behind your machine step by step.
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:
-
Their own direct storefront — a Shopify store under the Yoshan name
-
dongyicoffee.en.alibaba.com — their primary Alibaba trade account
-
gohaiyangai.com — B2B wholesale inquiry channel (this site)
For your range 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 for you 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 you would buy from 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 your machine does not contain lead, mercury, cadmium, hexavalent chromium, or specific flame retardants above legal limits.
Your certification documents are provided with every export order, including yours. 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. SKA verification requires demonstrated export history, buyer feedback, and response rate compliance audited by Alibaba’s team.
This matters to you because it is a third-party data point independent of the manufacturer’s own claims.
What Buyers Say
Named, story-length versions of this feedback: customer stories from Oman, Kenya and the Philippines.
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 buyer reported roasting around 450 kg 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 you will deal with you will deal with 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.
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 for your machine: 25–40 working days
-
Large industrial machines (120 kg+): 60–120 working days
-
Shipping to your port: sea freight worldwide, DDP/CIF/FOB Shenzhen available
-
Southeast Asia and the Gulf: 7–20 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.
Frequently Asked Questions
What do the machines cost?
Every model has a public factory price, ex-works: DY-1 USD 2,599, DY-2 USD 3,399, SD-3 USD 4,599, SD-1.5 Pro USD 5,399, YS-6 USD 7,499, SD-3 Pro USD 8,889, YS-12 USD 9,980, SD-6 Pro USD 12,999 with loader, SD-12 Pro USD 15,999, SD-15 Pro USD 16,999, YS-20 USD 18,999, SD-30 Pro full set USD 51,499, SD-60 Pro full set USD 61,999. The price guide lists all of them with what each includes.
How can I verify the factory without visiting?
Four checks that take twenty minutes: ask for the business licence and look up its code on China's enterprise register, checking that the scope says manufacturing; ask for a live video call from the welding bay and the test bench with today's date in shot; reverse-image-search the factory photos; and for a large order, book an independent one-day audit. The factory tour page sets out what to look for; we host all four.
What is the warranty, and what does support look like?
One year on the complete machine, extendable — two years for USD 699 on SD and YS models, and two or three years on the DY series for USD 299 or 799 — with support by WhatsApp and video call for the life of the machine and wear parts couriered worldwide. The after-sales guide shows four real support cases, which is a better test of the claim than any review.
Which machines are built here, and which are supplied?
The roasters — SD, YS and DY series, the sample roasters, and the destoners, loaders, smoke filters and afterburners — are built at the factory. The espresso machines and grinders on the site are sourced and supplied alongside them as a wholesaler, which we say on every page about them. Ask which is which on any quote and the answer is on it.
Can I speak to a customer?
We keep customer identities private unless they choose to be named, so we do not hand out contacts. What we can share is the documented cases — the Oman line, the support cases from the Philippines and Kenya — with names removed, and a video call with our engineers on the test bench with your own machine before it ships, which most buyers find answers the question the reference was going to.
Final Thoughts
A YOSHAN coffee roaster review, written honestly, is a list of things you can check: the licence, the certificates, the factory on a live call, the public prices, the warranty terms and the documented support cases. Check them all before the deposit — we would rather you did. Then send us your batch size, your supply and your country for a quote. Talk to our engineers.
