The float, which measures 8m x 2.5m, celebrates the 200th anniversary of the Bramley apple and depicts the variety's journey from "tree to table".
Some 5,000 Bramley apples supplied by Fourayes - the largest grower and processor of Bramley in the UK - will be distributed to members of the public during the procession, which is set to take place in the City of London on Saturday (14 November).
The decorating process took place at the college's Tonbridge campus last month. It was attended by WCF master Alan French along with liverymen Amanda Cottrell, Graham Collier and Mark Lumsdon-Taylor.
Lumsdon-Taylor is also director of finance and resources at Hadlow College.
