Steam-Humidifying & Sugar-Sanding Machine

Lightly moisten candies with steam and then evenly coats them with sugar, icing, or seasoning to prevent sticking and improve appearance and taste.

Applications

• Gummy candy with granulated sugar or coconut flakes.

• Sour belt candy with sour powder flavor

Working Principle

• Steam-Humidifying Zone – Low-pressure saturated steam (0.2–0.4 MPa) is dispersed as fine mist, raising surface temperature by 2–4 °C and creating a micro-wet layer without stickiness.

• Coating Zone – A rotating drum or vibrating pan evenly sprinkles sugar/seasoning; VFD speed control ensures >95 % coverage.

• Recovery Zone – Excess powder is collected via a cyclone separator and returned to the hopper for reuse 

• Steam Source: 0.3 MPa saturated steam, 5–15 kg/h.

• Control: Proportional valve + humidity sensor for 4–20 mA continuous output, eliminating on/off fluctuations.

Advantages

• Energy Saving: Steam humidification uses 30 % less water than water mist; >90 % powder recovery.

• Hygiene: Full stainless 304/316, GMP-compliant; optional CIP port.

• Quick Changeover: Flavor or powder change in <10 min with no cross-contamination.

• Automatic: Candy comes and automatic coating and exit.
