What is the maximum protein powder capacity and dispensing system configuration of the protein vending machine?

The protein vending machine features 8 independent powder canisters, each with a 3.8L volume, allowing stocking of 8 different base flavors or supplements simultaneously. It has 4 independent heavy-duty mixers to prevent cross-contamination and efficiently handle different flavors even during peak times. The machine holds 300 cups per refill and can serve over 500 drinks per full powder refill. The touch screen menu allows mixing any combination of the 8 powders, enabling over 20 different drink combinations. Recommended powder usage is 20-30g per drink in 350ml cups.

Can the protein/hydration machine be configured for hydration only without protein?

Yes. The machine has a large water barrel and multiple powder canisters (for protein, coffee, milk tea, etc.). For electrolyte/hydration water, there are two options:
(1) Powder Mixing – mix instant electrolyte powder with purified water inside the machine;
(2) Direct Input – fill the water barrel with premixed electrolyte water, and the machine acts as a pure water dispenser with no mixing.

Can the machine integrate with the Indian UPI payment system?

Yes. The machines fully support the standard MDB protocol. To integrate UPI, source a local MDB-compatible UPI payment module in India (e.g., from providers like Vendekin or Paytm). The device plugs directly into the machine’s MDB port. When a customer completes a UPI payment via QR code, the device sends an MDB signal to dispense the product. The key requirement is that the local payment device must support the MDB protocol.
