Small-Scale Solids Production Plant with Cooling Crystallization, Washing, and Drying in a Modular, Continuous Plant

Small-scale continuous apparatuses for solid product manufacturing are receiving increasing interest due to the demand fast market availability of specialty chemical products manufactured in integrated and modular processing plants. Relevant unit operations span from crystallization over solid–liquid separation filter cake washing drying. For this purpose, quasi-continuous belt crystallizer (QCFBC) was developed is presented here. The newly with positive pressure filtration (Δpmax = 0.8 bar), (V˙wash 55 mL·min−1), convection drying (Tdry 60 °C) have been individually characterized into apparatus that has modified operation. They were synchronized flexible cooling crystallization, enabling a seamless production process. Sucrose water used as model substance system. Long-term up 14 h successfully performed dry cakes (22.64 g ± 1.64 g·h−1) constant quality attributes (x50,3 216.095 14.766, 0.347 0.109, Yrel. 69.9% 5%, XRM mg·g−1 1.38 mg·g−1).
