Behaviour of falling-film freeze concentration of coffee extract
(Elsevier, 2014-11-01)
Article
Restricted access - publisher's policyThe behaviour of falling-film freeze concentration of coffee extract was studied through determining the solute inclusion in the ice produced in a single-plate freeze concentrator. The effect of the initial coffee mass ... -
Block freeze-concentration of coffee extract: Effect of freezing and thawing stages on solute recovery and bioactive compounds
(Elsevier, 2014)
Article
Open AccessCoffee extract was freeze-concentrated using the total block technique. The effects of four parameters were evaluated: the initial coffee mass fraction (5 and 15% w/w), the cooling temperature ( 10 and 20 C), the heating ... -
Calculation process for the recovery of solutes retained in the ice in a multi-plate freeze concentrator: Time and concentration
(2014-12-01)
Article
Restricted access - publisher's policyFractionated thawing was studied as a method to recover solutes incorporated in the ice obtained in a cryoconcentrator. Thawing times and solute concentration in the ice were determined at several thawing temperatures.; ... -

Effect of process parameters on progressive freeze concentration of sucrose solutions
(2017-05-25)
Article
Open AccessThe progressive freeze concentration of sucrose solutions was tested. The effect of the initial concentration of the solution (C0), the temperature of the refrigerant (T) and the stirring speed (¿) on the final concentration ... -
