Efficient and energy-saving evaporation concentrator for coffee liquid

1、 Product Introduction

2、 Working principle

1. Sealed feeding and mild preheating: Coffee liquid is stably fed into the concentration host through a food grade sealed feeding unit, and slowly heated to 50-65 ℃ (coffee flavor tolerance range) by the preheating system to avoid sudden temperature changes that may cause aroma substances to evaporate.

2. Circulating heating of energy carrying medium: Drawing on the principle of refrigeration cycle, the energy carrying medium completes a phase change cycle of "gaseous liquid gaseous" in a closed system. The heat energy released during the phase change process is uniformly transferred to the coffee liquid through indirect heat exchange, achieving mild heating without local overheating.

3. Vacuum low-temperature evaporation: The equipment quickly constructs a stable vacuum chamber (vacuum degree -0.05~-0.09MPa), reducing the boiling point of coffee liquid to 50-65 ℃, achieving rapid vaporization of water in a low-temperature environment, while avoiding high temperature damage to core active ingredients such as components and aromatic compounds.

4. Flavor recovery and continuous concentration: The secondary steam generated by vaporization carries the aroma of coffee, which is separated and concentrated by a dedicated flavor recovery device before being refluxed to the concentrated solution, greatly locking in the original flavor of coffee; The concentrated solution continues to circulate in the host until it reaches the target concentration (solid content of 30% -70%), and is finally automatically output by the closed discharge unit.

3、 Product advantages

1. High fidelity flavor activity: Accurately adapted to the characteristics of coffee liquid in a vacuum low-temperature environment of 50-65 ℃, avoiding the decomposition and oxidation of flavor substances, with a fragrance retention rate of ≥ 98%, no loss of activity, and a rich and pure taste of concentrated coffee.

2. High efficiency and energy-saving are outstanding: adopting energy carrying medium circulation heating technology, the thermal energy utilization rate is increased by more than 60% compared to traditional concentration equipment. Each ton of water evaporated consumes only 55-255 kW · h of electricity, and the operating cost is only one-third of traditional equipment, significantly reducing production energy consumption expenditure.

3. Exclusive adaptation for coffee liquid: Optimizing circulation flow rate and heat transfer structure based on the viscosity characteristics of coffee liquid, effectively solving industry pain points such as scaling and wall sticking; The concentration density can be flexibly adjusted to meet the production needs of different products such as instant coffee, concentrated coffee beverages, coffee extracts, etc.

4. Safe, compliant, and reliable: The fully enclosed system design avoids contact between coffee liquid and air, preventing oxidation, deterioration, and secondary pollution; The contact material is made of food grade 316L stainless steel, which meets GMP standards and food hygiene requirements. There is no risk of material precipitation, ensuring product safety.

5. Efficient and stable production capacity: The single effect evaporation capacity of a single device can reach 1000-5000L/h (depending on the model), supporting 24-hour continuous operation, with short concentration cycle and large processing capacity, meeting the large-scale production needs of the coffee industry.

6. Easy operation and maintenance: Adopting a PLC fully automatic control system, precise control of key parameters such as temperature, vacuum degree, concentration, etc., no manual intervention is required after one click start; Equipped with an online automatic cleaning system, the pipeline has no residue, the equipment has fewer vulnerable parts, the maintenance cycle is long, and the cost is low.
