2. The medical contact shock freezer of claim 1, wherein the shock freezer comprises a first pair of upper and lower freezer plates and a second pair of upper and lower freezer plates, the first pair being disposed above the second pair;

wherein the upper and lower freeze plates of the first pair comprise a fixed lower freeze plate and a movable upper freeze plate;

wherein the second pair of upper and lower freeze plates comprises a fixed upper freeze plate and a movable lower freeze plate;

and wherein, in the freezing position of the upper freezing plate, the contact surface of each upper freezing plate is arranged at an angle of at least 2 ° with respect to the horizontal.

3. The medical contact oscillation freezer of claim 2, wherein the lower freezer plate of the first pair of freezer plates and the upper freezer plate of the second pair of freezer plates are provided by a single, unitary freezer plate.

4. The medical contact shake freezer according to any preceding claim, wherein the contact surface of each upper freeze plate is arranged at an angle of between 3 ° and 10 ° relative to horizontal in the freeze position of the upper freeze plate.

5. The medical contact shake freezer of any preceding claim, wherein for at least one pair of freezer plates, the contact surface of the upper freezer plate and the contact surface of the lower freezer plate are each planar contact surfaces.

6. The medical contact shake freezer of any preceding claim, wherein for at least one pair of freezer plates, in their freezing position, the contact surface of the upper freezer plate and the contact surface of the lower freezer plate are parallel.

7. The medical contact shock freezer of any preceding claim, wherein for at least one pair of freezer plates, the movement between the loading position and the freezing position consists of a linear, vertical displacement of at least one of the freezer plates.

8. The medical contact shock freezer of any preceding claim, wherein for at least one pair of freezer plates, in their freezing positions, the contact surface of the upper freezer plate and the contact surface of the lower freezer plate are each arranged at an angle of about 5 ° relative to horizontal.

9. A method of shock freezing a plurality of individual bags containing a medical liquid, the method comprising:

arranging the individual bags side-by-side, adjacent to each other, between an upper and a lower freeze plate of a contact shaker freezer, wherein the plates are arranged in a bag loading position;

subsequently bringing the freeze plate closer to a freezing position by moving at least one of the upper freeze plate and the lower freeze plate to clamp each individual pocket in contact with the contact surface of the upper freeze plate and the contact surface of the lower freeze plate, wherein the each individual pocket is held in an angled pocket configuration at an angle of at least 2 ° relative to horizontal;
