Market Size and Where the Machines Sit
Smart beverage machines cover fresh coffee, juice, milk tea, and vending-style dispensers in offices, malls, airports, hospitals, and schools. iResearch put China’s freshly made drinks market — coffee and tea included — above RMB 600 billion in 2023. Self-service fresh-brew machines and smart beverage venders together passed 800,000 units, growing about 18% a year. Most of them stand in public places with no fixed Wi-Fi, so 4G/5G is the usual link. The share online rose from about 60% in 2020 to more than 85% in 2024.
Core Pain Points
Machines that are hard to service: Units sit in different cities and different corners. Faults, empty ingredient canisters, and a lack of cups still depend on someone walking the route, so response is slow and the visit is expensive. Restock and inventory: Beans, milk powder, syrup, cups, and straws have to be known as they run down. A restock alert and a sensible route cut both stockouts and waste. Payment and the business around it: Scan-to-pay, membership offers, and coupons need the machine online. Sales and machine status are what decide the next site and the next menu.
Technical Standards and Terminology
Food-safety rules in play include GB 4806, Food Contact Materials, and GB 5749, Standards for Drinking Water Quality. Common terms: 4G Cat.1 (low- to mid-rate cellular, a fit for a beverage machine); M2M (device-to-platform communication); IoT (Internet of Things); SaaS (device management and the operations platform); RFID (traceability for ingredients and consumables). Uplink is 1–5 Mbps. A payment is expected in under 3 seconds. A machine typically uses 80–200 MB a month.
Who Builds and Who Operates
The chain runs from machine makers (Kafei Technology, Ubox, and Bianlifeng) through fresh-drink brands that co-brand machines (Luckin Coffee, Heytea, and Mixue) to the connectivity layer. Kafei Technology and Ubox lead fresh-brew coffee machines. One operator connected 3,000 of them over 4G. Ingredient levels and fault codes report as they change, and restock tickets go out on their own. Stockouts fell by about 40%, and maintenance cost fell by 30%.
Where IoT Is Used
Status on the network: The machine reports run state, sales, fault codes, and ingredient levels over 4G/5G, and it supports anomaly alerts, remote diagnosis, and over-the-air updates.
Restock and routing: Ingredient and consumable levels come back as they change. A low reading opens an alert and lines up with the restock ticket and the delivery route.
Operations analysis: Sales and how often a machine is used decide whether a site stays, which drinks remain on the menu, and which promotions are worth running.
Where the Market Is Heading
Machine makers are tying more tightly to coffee and tea brands. AI recommendations and made-to-order drinks are showing up. Machines are being linked to delivery and group-buying apps. Ingredient traceability and digital food-safety records are moving from a slide into the machine itself.
Summary
A beverage machine used to be a box that an operator visited. It is becoming a node on a platform, and that only works if the cellular link is there for maintenance, restock, and the sales record. SimtoLink supplies 4G/5G IoT SIM cards and communication modules for this sector, so machines stay online and operators can run more sites with a smaller field team.
