The support plate (2) with the motor (3) rests on at least three horizontally elastically movable bearing elements (6), whose points of attachment to the base (1) and to the support plate (2) are chosen such that the support plate (2) with the microplate (7) in the idle position assumes a specified position in the X-Y plane due to the reset force of the bearing elements (6), and in the shaking mode, as a result of the lateral, directionally identical deflection of the bearing elements (6) effected by the unbalance of the motor (3), performs a horizontal, non-torsional shaking movement against the reset force of the bearing elements. In the process, all sample containers of the microplate (7) describe an identical orbit in the X-Y plane and an identical energy for mixing is imparted to all sample containers.

This invention relates to a process and / or method and associated apparatus for use in spray freeze drying a fluid substance such as fruit juice, pharmaceuticals, nutraceuticals, tea and coffee. A fluid substance is sprayed (atomised) and reduces in temperature to below its eutectic temperature; thereby inducing a phase change of fluids in the fluid substance. The atomised fluid substance (AFS) is then subjected to a vacuumous drying chamber in which the AFS is subjected to an energy source to assist sublimation of fluid from the AFS as it is conveyed through the chamber. Such an energy source can provide a temperature gradient through which the AFS passes and is exposed to, all carried out so as to preferably minimise or reduce the likelihood of degradation of the substance being dried (reducing the fluid content).
