The Mix Station is a station in Papa's Freezeria (and the HD and to Go! versions of the game).
Here, players blend the combined base, mixable, and syrup ordered by the customer to the specific blend (smooth, regular, or chunky) he or she chose when placing the order.
At the start of the game, customers will order their sundaes with regularly blended. When players achieve Rank 10 in the game, some customers will begin ordering their desserts with chunkier mixables (chunky blend). This requires that the sundaes spend less time under the mixers than regularly blended sundaes, which in turn the station where you leaves larger pieces of the mixable item.
When players reach rank 20 in the game, some customers will begin ordering their desserts "smoother" (smooth blend). This requires that the constructed dessert spend more time under the mixers than the regularly blended sundaes, which in turn breaks the mixable ingredient to smaller bits, resulting in a "smoother" dessert.
There are four blenders in the game, and players can buy boosters for this station to speed up the blenders. There are meters for each blender that come with the boosters. Pressing down on the booster (with the mouse) will cause the blender to "overheat." Once a blender overheats, it becomes inoperable (until the meter returns to normal) and the sundae may have to be moved to another blender.
In Papa's Freezeria To Go!, boosts are still available for purchase, but the blenders will not overheat when holding the button down (with finger or stylus).
