STA Impianti, 5 Kilos, 5-7 kg Capacity, 220V, Gas Heated

STA Impianti, 5 Kilos, 5-7 kg Capacity, 220V, Gas Heated

Description

  1. Overview
    1. Sta is a manufacturing group in Italy composed of seasoned engineers from major old Italian roasting machine makers.
    2. Hot air is introduced into the top of the roasting chamber, pulled through the turbulating coffee, and exits through drum perforations into the bottom.
    3. This design is friendly to blending formulas and produces smaller chaff, resulting in a cleaner roast than some solid drums.
    4. Produces big naturally developed beans with a very even roast.
    5. Roasting machines line particularly suitable for little production activities of high quality roasted coffee, such as shops, pastries, or artisan laboratories.
    6. Small size, technologically advanced, ideal for production of selected coffees in little quantity.
    7. Made with the same reliability and security features as bigger industrial roasting machines.
    8. Available with heating generator type gas burner (also available by electric resistances) and automatic control system with semiautomatic management.
  2. Specifications
    1. Roaster capacity: 5 kg, max 7 kg cycle.
    2. Roasting cycle: 9 minutes to 20 minutes.
    3. Raw coffee processing per hour: 20 kg to 30 kg.
    4. Installed electric power: 0.9 kw, singlephase 220 volts, 50 hz.
    5. Thermal power (natural gas or lpg): 8000 kcal/h.
  3. Main Components
    1. Hopper of charge in stainless steel.
