The invention relates to a device for comminuting dry ice granules, comprising a housing having a flow channel for dry ice granules to be applied to a surface to be cleaned by means of pressurized gas and a first comminution member for comminuting the dry ice granules to be dispensed. In order to provide such a device by means of which various degrees of comminution of dry ice granules can be achieved in a simple manner, the invention provides that the device has at least a second comminution member that can be disposed in the housing in a position in which, in combination with the first comminution member, a total degree of comminution can be achieved that is greater than the individual degree of comminution achieved using the first comminution member alone. The invention further provides a dry ice dispensing arrangement for dispensing a mixture of pressurized gas and dry ice granules using such a device.
